Abstract: A poly(vinyl chloride) resin composition comprised of an admixture of poly(vinyl chloride) resin and a clear or translucent polymeric material comprised of a non-uniform copolymer comprised of acrylonitrile, styrene and acrylate ester. The clear polymeric ASA material is a good impact modifier for PVC. The admixture contains from 3 to 15 percent by weight, based on the admixture, of the clear polymeric material. The clear polymeric material has a weight ratio of acrylonitrile and styrene acrylonitrile, styrene and acrylate ester which is between about 40 to 60 and about 60 to 40. The PVC resin combination, in dry form, can be conventionally hot processed or fabricated.

Abstract: A highly crystalline non-uniform copolymer comprised of ethylene and acenaphthylene, which lacks the independent beta thermomechanical transition in the torsion pendulum loss-modulus curve possessed by known copolymers of ethylene. The non-uniform copolymer being photodegradable. A compatible blend of the polymeric material and high density polyethylene or the polymeric material and low density polyethylene has a higher use temperature than the particular polyethylene by itself.A though semi-crystalline, high-modulus, semi-elastic, non-uniform terpolymer comprised of ethylene, acenaphthylene and a different alpha-olefin, such non-uniform terpolymer being more elastic than polyethylene.

Abstract: Polymers of at least two different alpha monoolefinic monomers capable of polymerizing with themselves and each other. The polymers comprise a plurality of polymer chains along which the proportion of mer units provided by a first such monomer for a given first chain length gradually increases as the proportion of mer units provided by a second such monomer along the first chain length gradually decreases to a second chain length along which the proportion of mer units provided by the first and second monomers, respectively, remain substantially constant throughout said second chain length. Also, included are polymers of this type wherein the polymer chains comprise a third chain length along which the proportion of mer units provided by the first monomer is greater than the minimum proportion of the same type of mer units in the given first chain length and remains substantially constant throughout the third chain length.
