Certain physical properties, such as heat-distortion temperature and flexural modulus, of certain commercially available thermoplastic resins are improved by blending with polyindene or coumarone-indene resins.

Blends of a copolymer of methyl methacrylate and styrene with an acrylonitrile-styrene copolymer have improved optical, mechanical and gas barrier properties as well as improved processability.

Copolymer blends

Polymeric compositions having high heat-distortion temperatures which function as gas and vapor barrier materials which are composed of an olefinically unsaturated nitrile, such as acrylonitrile, and indene are produced by the copolymerization of said olefinically unsaturated nitrile and crude indene which can be derived from various sources.

Thermoplastic resin blends containing polyindene or coumarone-indene

Light colored, high molecular weight thermoplastic xylene-formaldehyde polymers are prepared by reaction of substantially equimolar amounts of xylene and formaldehyde in the presence of a strong acid catalyst by the exclusion of air from the reactor.
