Abstract
Abstract A chlorine-free acrylic ester/vinyl nitrile unvulcanizable copolymer and a cross-linked acrylic ester/vinyl nitrile chlorine-free copolymer exhibit a combination of clarity, good temperature flexibility and high temperature strength. The copolymer has good sprayability when diluted with 70 to 90 weight percent of certain non-aqueous solvents. The cross-linked clear interpolymer is a thermoplastic which can be fabricated into a variety of useful products.
