Abstract: The present invention provides a thermoplastic resin composition comprising (a) 100 parts by weight of a resin selected from the group consisting of polypropylenes and copolymers composed mainly of propylene, (b) 5 to 350 parts by weight of a resin selected from the group consisting of polyethylenes and copolymers composed mainly of ethylene, the resin having been prepared using a single site catalyst, and (c) 5 to 200 parts by weight of an ionomer resin or its ester. The present thermoplastic resin composition is excellent in mechanical properties and heat bonding property to various resins, and causes no bleeding-out of softening agents, thereby the softness of the shaped articles obtained from the composition can be easily controlled. The present invention also provides a laminated article comprising a layer of the resin composition .
Abstract: This invention is directed to a process for the rapid in-situ curing of polymerizable materials to provide macro-molecular networks and articles of manufacture that are “morphology-trapped”; that is, they exhibit a fixed phase morphology and/or molecular orientation that is locked in by the curing step. The process includes the steps of mixing together a dead polymer or a prepolymer, a reactive plasticizer or a diulent, and an initiator to give a polymerizable composition; further processing the mixture in order to achieve a desired phase morphology and/or moelcular orientation of the polymeric constitutents; shaping the polymerizable composition into a desired geometry; and exposing the polymerizable composition to a source of polymerizing energy, without mixing to give a final product with the desired phase morphology and/or moelcular orientation locked in place.

Abstract: The object of the present invention is to provide a molding thermoplastic resin material giving resin mold whose quality and value are substantially equal to original resin mold even in a case where said resin mold is recycled.
To attain said object, olefin group rubber and/or acrylic rubber to which monomer(s) being the same or similar monomer as (to) monomer(s) composing said molding thermoplastic resin material is(are) graft-copolymerized to give said rubbers compatibility with said molding thermoplastic resin material is(are) added in said molding thermoplastic resin material to improve said equal quality recycling property (property that quality and value are substantially equal to original thermoplastic resin mold even in a case where said thermoplastic resin mold is recycled).
Abstract: An ink wastage absorber is made from a flexible polyurethane foam having an air-permeability of 1.0 cc/cm2/sec or more, or is made from a flexible polyurethane foam produced by using a foamable raw material containing a polyol, an isocyanate, a catalyst, and a foaming agent, wherein the polyurethane foam is impregnated with a surface active agent. An ink supporter includes an ink permeation member provided at a portion corresponding to a printer head and an ink absorbing member being in contact with the ink permeation member.
Abstract: The invention provides composite components constructed of a layer i) comprising short fiber reinforced PU and having a paintable surface, and a layer ii) comprising long fiber reinforced polyurethane, and also provides a process for producing them, and provides for their use as exterior bodywork parts.

Abstract: The objective of the present invention is to provide a production method by which a polymer of a functional group-terminated vinyl monomer can be easily and practically produced.
Further, it is another object of the present invention to provide a functional group-terminated vinyl polymer which is useful as a material for the production of various functional products.
The first aspect of the present invention is concerned with a production method of a functional group-terminated vinyl polymer comprising a step of synthesizing a halogen atom-terminated vinyl polymer by the radical polymerization reaction of a vinyl monomer in the presence of a halogen compound and a step of introducing a functional group to a terminus by substituting a functional group-containing group for the terminal halogen atom of said vinyl polymer.
Abstract: The present invention relates to articles having a printed surface as well as flexible coating and film compositions that are printable in combination with exhibiting stain resistance. The composition comprises a hard component having an elongation of less than about 150%, a soft component having an elongation of greater than about 200%, and a cross-linking agent. The hard component preferably comprises a thermoplastic polyurethane, acrylic polymer, polymeric polyol or mixture thereof. The soft component preferably comprises a thermoplastic urethane, polymeric polyol, or mixture thereof; whereas the cross-linking agent is preferably an isocyanate.
Abstract: The invention provides an improved method of graft polymers comprising providing an emulsion comprising at least one or more first monomer (a), at least one or more second monomer (b), and at least one graft material (c). The emulsion is subjected to conditions such that it undergoes simultaneous free radical polymerization and grafting. One or more first monomer (a) is unsaturated and is free of any functional groups reactable with a functional group Fb of monomer (b) or a functional group Fc of graft material (c). Monomer (a) may optionally comprise a functional group Fa which is not reactive with either functional group Fb or Fc. Monomer (b) is unsaturated and comprises a functional group Fb reactive with functional group Fc. Graft material (c) comprises a compound free of unsaturation and comprising a functional group Fc reactive with functional group Fb, and a graft moiety.
Abstract: Improved flame retardant compositions suitable for insulating wire and cable products comprised of ethylene-alkoxy silane copolymer, halogenated organic compound, antimony trioxide, silane condensation catalyst and magnesium hydroxide are provided. Additionally, antioxidant(s), other mineral fillers and other conventional compounding ingredients may be included in the formulations. The compositions have good processability and are capable of being cured under ambient conditions to provide products which meet all of the specifications of SAE J-1128 for thin wall crosslinked polyolefin low tension primary cable insulation. Wire and cable products comprising a metal conductor coated with from 2 to 100 mils of the flame retardant insulation are also disclosed.
