Abstract: An ink composition for use in ink jet printing to print images on a vinyl substrate which contains vinyl polymers and plasticizers, the composition being formulated to include a resin component having a pendant amino group, a dye, and a carrier. The composition can be applied to vinyl substrates without fading with time, due to degradation of the printed images by plasticizers present in the vinyl substrate.

Abstract: A thermoplastic molding composition comprising a terpolymer having a weight ratio of from about 20 to 50, preferably 20 to 30, parts .alpha.-methylstyrene, about 79 to 40, preferably 73 to 67, parts methyl methacrylate and about 1 to 10, preferably 3 to 6, parts N-vinyl-2-pyrrolidone. A particularly preferred terpolymer composition includes 25 parts .alpha.-methylstyrene, 70 parts methyl methacrylate and 5 parts N-vinyl-2-pyrrolidone. Thermoplastic molding compositions embodying this invention are characterized by excellent transparency, high flow rates and resistance to deformation at high temperatures.

Abstract: The present disclosure concerns a composition comprising a copolymer product of a vinyl aromatic monomer selected from the group consisting of .alpha.-methylstyrene, 2-methylstyrene and tertiary butylstyrene, methyl methacrylate, and acrylonitrile or methacrylonitrile monomers which are polymerized at regulated conditions to produce a terpolymer having a disclosed weight ratio of vinyl aromatic to methyl methacrylate to acrylonitrile or methacrylonitrile. The present composition is thought to be useful for applications in which clear solvent resistant polymeric compositions are required which also have high heat resistance evidenced by high heat deflection temperatures. Such composition possesses unique properties which can be exploited through recognized molding procedures to produce many household appliances which must be subjected to high temperatures, possess substantial clarity and reasonable chemical inertness.
