Abstract: A resin suitable for use as a photoresist that is the esterification product of an o-quinonediazide compound and an aromatic novolak resin. The aromatic novolak resin may be the condensation product of a reactive phenol with a bis(hydroxymethyl)phenol or an aromatic aldehyde. The aromatic resin may be chain extended by further reaction with an additional aldehyde. The resin has a maximum of 20 percent of its phenolic hydroxyl groups esterified with the o-quinonediazide sulfonate compound.
Abstract: Reinforced polymer composites having a uniform mixture of reinforcing fibers having a polymodal length distribution and having polymer particulates are provided exhibiting a good balance of impact strength and processability/formability. The composites are prepared by forming a dilute aqueous slurry of a solid heat-fusible organic polymer and a reinforcing material having a polymodal length distribution, agitating the slurry and then dewatering the slurry to provide a mat of thermoplastic polymer particles and reinforcing fiber. The mat is dried and then stamped under pressure and heat to consolidate the thermoplastic material and form a sheet-like composite structure.

Abstract: Melamine thermoset resins with low formaldehyde volatiles display a remeltable solid phase, a liquid phase, and a cured solid phase. These resins are formulated from melamine, glycerol as a cross-linker, polyvinyl acetate homopolymer, and sucrose as a formaldehyde scavenger in an aqueous solvent. Optional ingredients for controlling the resin adhesive's crosslinking and/or curing rate include ethylene glycol, a pH buffering system such as citric acid/sodium diacetate, and an amine block sulfonic acid salt. The compositions are particularly useful as resins for coatings, saturations, and bonding of synthetic fibers into fabric mats, and display thermal stability and rigidity at temperatures ranging up to 370.degree. C.

Abstract: The present invention provides a method for recycling a polymer crosslinked through acyl carbamate bond. Disclosed is a re-crosslinkable composition obtained by adding an alcohol to the polymer crosslinked through acyl carbamate bond and heating.
Abstract: A light scattering light guide, which is capable of converting a light flux of a relatively small cross-sectional area into a light flux of a relatively large area with high efficiency and uniformity, manufacturing method thereof, and applied optical apparatuses such as backlight light source apparatuses and light branching/mixing devices which make effective use of the characteristics of said light scattering light guide. Such light scattering light guide is obtained by utilizing various structures with irregular refraction indexes generated in the process of polymerization of organic materials.
Abstract: The present invention relates to a method of treating a packaging element, specially a sealing element, comprising the coating with a polymer film of at least those parts of said element which are liable to be in contact with the products packaged, wherein said coating is produced by polymerization, assisted by cold-far-remote-plasma, of at least one monomer chosen from siloxanes and silazanes of formula: ##STR1## in which: A represents an oxygen atom or the NH group and;R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 represent, independently, a hydrogen atom or an alkyl or alkoxy group having from 1 to 4 carbon atoms, preferably a methyl group. Application: stoppers intended for a medical or pharmaceutical use.

Abstract: A building material including reclaimed leather, neoprene, and nylon. The reclaimed materials are shredded and blended together with a matrix material. The matrix material is a polymeric adhesive. The chips with the matrix material are heated to form a uniform mixture. The uniform mixture is then molded into the building material sheets.
Abstract: Disclosed herein is a gas barrier film formed from a mixture containing polyvinyl alcohol and a partially neutralized product of poly(meth)acrylic acid in a weight ratio of 95:5 to 10:90, and having an oxygen permeability constant of 1.25.times.10.sup.-3 ml(STP).multidot.cm/m.sup.2 .multidot.h.multidot.atm{Pa} or smaller as measured under conditions of 30.degree. C. and 80% relative humidity. A production process of the gas barrier film, in which a film formed from a mixture containing polyvinyl alcohol and a partially neutralized product of poly(meth)acrylic acid is subjected to a heat treatment under specific conditions, is also disclosed. The gas barrier film of the invention is excellent in water resistance and oxygen gas barrier property, free of any chlorine atom, and scarcely colored.
Abstract: An acid cured coating composition containing a hydroxyfunctional acrylic or polyester resin and a 1,3,5-triazine-2,4,6-tris-carbamate. Also provided is an acid cured coating composition containing a hydroxyfunctional acrylic or polyester resin, a crosslinking agent such as a melamine-formaldehyde or a related aminoresin, and a co-crosslinking agent derived from a triazine tris-carbamate such as 2,4,6-tris-(butoxycarbonylamino)-1,3,5-triazine. Also provided is an improved method of coating using the above coating compositions. The coating compositions described in this invention have lower cure temperatures, lower formaldehyde emissions during cure, and produce films and objects which have superior environmental etch resistance than the conventional melamine-formaldehyde coatings which do not have a triazine tris-carbamate co-crosslinker.
Abstract: A resin composition comprises an EVOH (A) and a thermoplastic polymer (B) having at least one functional group selected from the group consisting of boronic acid group, borinic acid group and boron-containing groups convertible into boronic acid group or borinic acid group in the presence of water. The composition may further comprise a thermoplastic polymer (C) other than (A) or (B). The resin compositions thus obtained have good compatibility and give molded products having superior transparency and good mechanical properties.
Abstract: Polymer blends of at least one polar polymer are prepared by admixture with a poly(vinyl alcohol) and a (meth)acrylate copolymer also containing vinyl amide and/or unsaturated acid units. The ternary compositions have attractive processing and performance properties.

Abstract: The present invention relates to improved acid etch resistant polymers and coatings, and their method of preparation whereby polyurethane polyols, which because of long alkyl side chains that include a single ether group in the chain, when reacted with a melamine compound, such as, hexakismethoxymethylmelamine, form coatings that have excellent solubility in hydrophobic solvents and provide films with excellent acid etch resistance. The polymers, because of their excellent acid etch resistance and exterior durability can be used for automotive clear coats or single coats.
