Abstract: To provide practical corrugated cardboard pallets that cope with rain, humidity or the like and water-resistant corrugated cardboard for use as the material thereof. Water-resistant paper is used for base paper for corrugated paperboard and base paper for flat paperboard, and cornstarch glue containing 7 to 10 percent by weight modified ketone resin is used as an additive for water-resistance, all of which are used to manufacture the corrugated cardboard. Such corrugated cardboard is used at least in the beam portion to produce a pallet.

Abstract: The present invention is an apparatus and process for cleaning substrates using dense fluids under the influence of centrifugal force and dense fluid phase changes. A perforated centrifuge drum operates within a pressure vessel having drains and fill ports. System controls include a high optical sensor, a low optical sensor, a pressure transducer, and a thermocouple. An external dense fluid cleaning and management system exchanges dense fluid and gas with the pressure vessel via the drain and fill ports. Dense fluid centrifugal separations prevent pooling and supercooling of liquid carbon dioxide avoiding recontamination of the substrate. The present invention can perform solvent-aided separation processes including liquid-liquid, liquid-supercritical-fluid, froth flotation and centrifugal phase-shift separations.

Abstract: Disclosed is a cellular thermoset poly(dicyclopentadiene) having a density of from about 0.2 to about 0.85 g/ml.

Abstract: Disclosed is a transition metal component of a Ziegler-Natta catalyst which is composed of a titanium halide deposited on an essentially anhydrous magnesium chloride support. An improved support is prepared by contacting a hydrocarbon solution of magnesium alkanoate and a hydrocarbon solution of alkylaluminum dichloride in a liquid hydrocarbon reaction medium containing alkylaluminum dichloride and alkylaluminum alkanoate chloride. After workup and treatment with the titanium halide, the transition metal component is used in the Ziegler-Natta catalysis polymerization of 1-olefins. The resulting polyolefins have a narrow particle size distribution and a high bulk density.

Abstract: Disclosed is an improved method of making a cellular crosslinked polymer with a metathesis-catalyst system where a metathesis-catalyst is activated with an alkylaluminum iodide compound.In a preferred embodiment, two parts of the metathesis-catalyst system form the basis for two solutions, a catalyst/monomer solution and an alkylaluminum iodide activator/monomer solution. At least one solution also contains a blowing agent. The solutions are combined in one place, such as the mixing head of a reaction injection molding machine, and then injected into another place, such as a mold, where the monomer reacts to form a cellular crosslinked polymer.

Abstract: Halogen-containing polymers can be crosslinked by heat-curing with a crosslinking system made up of a crosslinking agent which is either a polymercaptan or an ester derivative thereof, a basic material and a hydrated salt. When the hydrated salt is chosen so that it releases its water of hydration during heat-curing the rate of crosslinking is enhanced.

Abstract: Disclosed is the incorporation into a two-part metathesis-catalyst system of a halogen containing hydrocarbyl additive, where the hydrocarbyl additive contains at least one trihalogen substituted atom or at least one activated halogen atom. The use of this catalyst system to polymerize dicyclopentadiene results in a thermoset polymer containing low levels of residual monomer. Also disclosed is a preferred embodiment of dicyclopentadiene polymerization where the two parts of the metathesis-catalyst system, plus dicyclopentadiene are combined in the mixing head of a reaction injection molding machine and then injected into a mold where the dicyclopentadiene rapidly sets up into a thermoset polymer.

Abstract: Disclosed is absorbent material composed of a consolidated blend of spurted polyolefin pulp, treated with an anionic or nonionic wetting agent substance having a molecular weight less than about 8000, and wood fluff pulp. The absorbent material exhibits a desirable combination of strength, rate of absorbency and total absorbency.

Abstract: The adhesion of fibrous polymeric aromatic amide reinforcing material to rubber stock is improved by treating the fibrous material with an aliphatic sulfonylazide having the general formula R(Cl).sub.x (SO.sub.2 N.sub.3).sub.y, where R is an aliphatic or cycloaliphatic hydrocarbon radical containing at least 5 carbon atoms, y is from about 1 to about 4 and x is from 0 up to about 2y; heating the treated fibrous material at a temperature and for a period of time sufficient to decompose substantially all the sulfonylazide groups; then coating the resulting material with an adhesive; and finally, embedding the coated material into rubber stock which is then vulcanized.

Abstract: In an improved adhesive process the amount of azidosilane coupling agent necessary to adhere a siliceous material to a polymer is reduced. The siliceous material, the azidosilane coupling agent and the polymer are admixed with an organosilicon compound and then heated at a temperature and for a time sufficient to decompose the azide groups of the azidosilane coupling agent. The reduction in the amount of azidosilane coupling agent is accomplished without adversely affecting the adhesion of the polymer to the siliceous material. Also disclosed are the products thus produced.

Abstract: Disclosed is the improvement in post-exposing relief printing plates prepared from photosensitive polymeric compositions which comprises immersing the relief printing plate in a dilute aqueous solution of a persulfate salt and a sufficient amount of a water-soluble carboxylic acid to provide a pH of about 1.5 to about 2.5 during exposure to actinic radiation.

Abstract: Stable aqueous dispersions of polyolefin fibers are formed by contacting the fibers with an aqueous solution of a cationic copolymer of an acrylamide and an acrylate or methacrylate ester, the pH of the aqueous solution having been adjusted to be in the range of from about 9.5 to about 12 either prior to, during or after contacting the fibers with said solution. An exemplary copolymer is that formed by the copolymerization of acrylamide and .beta.-methacryloyloxyethyltrimethylammonium methyl sulfate.

Abstract: A fruit suspension which contains a mixture of from 70% to 30% low methoxyl pectin and from 30% to 70% xanthan based on the total weight of gum added, preferably a 50:50 mixture, is effectively stabilized. Such a mixture is particularly useful in stabilizing the fruit suspension employed in sundae style yogurts because it eliminates problems with unwanted gelatin and fruit float.
