Abstract: Polyisobutylene oxide polymer moldings containing 70 wt. % or more of isobutylene oxide, are prepared by heating the polymer to a temperature above 170.degree.C and then quickly cooling the same by contacting it with a coolant to obtain crystalline resin having a diffraction peak at about 2.theta.=12.degree. in the X-ray diffraction pattern of the resin.

Abstract: A styrene-acrylonitrile resin composition having a good parting property comprising a styrene-acrylonitrile resin having blended therein, an .alpha.-olefin epoxide of the following formula: ##EQU1## wherein R and R' each is hydrogen or a straight-chain alkyl group, with the proviso that the sum of the carbon atoms in R plus R' is from 8 to 13, preferably 10 to 12.

Abstract: An ABS resin composition is disclosed, adapted for rotational molding (rotocasting), which comprises an ABS resin of from minus 10 to plus 100 mesh size particles having uniformly dispersed and adhered to the surface of the particles an organic compound of a particle size of minus 100 mesh having a melting point of 100.degree.C to 250.degree.C and a decomposition point above 200.degree.C, the weight ratio of resin to organic compound being 100 to 0.1 - 5.0.

Abstract: Molding compositions having improved properties for low-pressure, low-shear molding techniques are prepared by carrying out a two-stage polymerization of an initial mixture comprising a polymerizable monomer selected from the group consisting of (1) a polymerizable aromatic monoalkenyl monomer or (2) a mixture of such aromatic monoalkenyl monomer with another polymerizable monovinyl monomer; in the presence of a butadiene rubber elastomer under bulk polymerization conditions, followed by suspension polymerization conditions; the process being characterized by the incorporation into the initial mixture of 1 to 10 wt. %, based on the polymerizable monomers, of a straight chain saturated polyester having an average molecular weight of 1,000 to 50,000.

Abstract: A coating composition is disclosed for producing alcohol-insoluble films which comprises a mixture of an alcohol-soluble nylon copolymer, an alcohol-soluble alkoxymethylated nylon and an acid catalyst.
