Abstract: A resin composition comprising a polyolefin resin containing a processability enhancing proportion of a compound of the formula RCONHCH.sub.2 CH.sub.2 CONHR', wherein R and R' are derived from a C.sub.8 -C.sub.24 fatty acid.

Abstract: Linear low density polyethylene and copolymers of ethylene with at least one alpha-olefin containing 3-8 carbon atoms having increased temperature of crystallization and rate of crystallization are prepared by incorporating a proportion of highly isotactic polypropylene therein with the nucleating compound dibenzylidene sorbitol or phenyl phosphate compound.

Abstract: Fibrillated polyester textile materials and methods for producing same are disclosed. Such fibrillated polyester textile materials have a body portion formed of a plurality of polyester filaments in which the filaments contain a plurality of fibrils on the convex side portion of the filament curvature pointing away from the body portion of the textile material. The methods disclosed include treating the polyester textile material with a swelling agent and abrading the resulting material to produce the desired fibrillated polyester textile material. Also disclosed is a unique method wherein the molecular weight of the polyester employed to make up the textile material is lowered prior to the polyester textile material being treated with the swelling agent and abraded.

Abstract: Nitrogen-containing compounds are provided having the following formula: ##STR1## where R.sub.1, R.sub.2 and R.sub.3 are independently selected from H and ##STR2## wherein R.sub.4 and R.sub.5 are each independently selected from H and a lower alkyl group having from 1 to about 4 carbon atoms.

Abstract: Novel polyamine cycloaliphatic compounds are provided in which the polyamine substituted cycloaliphatic compounds contain at least two alkyl substituted amino moieties represented structurally as ##STR1## wherein n is an integer of from 0 to about 3, R and R.sub.1 are ##STR2## and R.sub.2, R.sub.3 and R.sub.4 are H or alkyl moieties containing from 1 to about 10 carbon atoms. The polyamine substituted cycloaliphatic compounds are further characterized in that at least one R or R.sub.1 is ##STR3## such compounds are especially useful as epoxy curing agents.

Abstract: A shapeable thermoplastic resin composition is provided which comprises a thermoplastic, condensation polymer or polymer blend substantially free of olefinic unsaturation having an intrinsic viscosity of from about 0.1 to about 5 and from about 0.01 to 2 percent by weight of a cyclic acetal as a nucleating agent.

Abstract: Nitrogen-containing compounds are provided which may be represented structurally as: ##STR1## wherein R.sub.1 and R.sub.2 are each independently selected from hydrogen and lower alkyl and R.sub.3 is selected from hydrogen, lower alkyl, aryl and ##STR2## wherein R.sub.4 is selected from H and lower alkyl.

Abstract: A process is provided for preparing non-aromatic, nitrogen-containing compounds represented structurally as: ##STR1## wherein R is CN or CH.sub.2 NH.sub.2, and R.sub.1 and R.sub.2 are hydrogen or C.sub.2 H.sub.5 --CH--CH.sub.2 R wherein R is as previously defined, which comprises reacting an effective amount of a nucleophilic agent with 2-pentenenitrile under conditions whereby said 2-pentenenitrile undergoes an addition reaction with said nucleophilic agent to form said nitrogen-containing compounds. Also provided is a novel process for curing polyepoxides using di- and polyamine epoxy curing agents.
