Abstract: A thermoplastic elastomeric composition is provided exhibiting reduced levels of hardness and enhanced levels of elongation. The composition contains a chlorinated polyolefin and graft copolymer having a rubber substrate present at a level of 65 to 90 percent by weight based on the total weight of the graft copolymer. Preferably the graft copolymer is an acrylonitrile-butadiene-styrene graft copolymer and preferably the chlorinated polyolefin is a chlorinated polyethylene having a high molecular weight and a relatively low chlorine level. The composition is useful for making molded articles such as interior automotive components requiring high elongation and tear resistance, reduced hardness and often high strain recovery.

Abstract: An stabilized thermoplastic composition comprising a stabilizing amount of a phosphite of the formula: ##STR1## R.sub.1 is independently selected from the group consisting of alkyl groups having from 1 to 9 carbon atoms, Y is independently selected from the group consisting of hydrogen, halogen, or alkyl; and the --O--X groups are positioned at the respective ortho- or para- positions with respect to the diphenyl linkage, the remaining ortho- and para- positions with respect to the --O--X linkage being occupied by R.sub.1 whereby the --0--X groups are hindered by the presence of at least one R.sub.1 group; R.sup.

Abstract: Melt extrusion processes involving phosphite stabilized polyolefin compositions subject to solid by-product formation during melt extrusion are improved by the addition of a metal salt of a lactic acid to the composition. The processes involving the improved compositions exhibit reduced levels of screen pack plugging during fiber and film extrusion processes than that achieved with fatty acid salts, such as calcium stearate.

Abstract: An organic phosphite composition is provided comprising organic phosphite particles having organic phosphite cores coated with an aminofunctional organic polysiloxane. Blends of the phosphite and the aminofunctional organic polysiloxane are also provided. The phosphite particles exhibit high levels of resistance to hydrolysis and are useful as antioxidant additives for thermoplastic compositions.

Abstract: The invention relates to polymer mixtures which comprise a polyalkylenephthalate ester and a cyclic imino ether functionalized polystyrene. Layers can be manufactured from these mixtures. Said layers show a good bonding to layers of polystyrene.
