Abstract
There is disclosed a calenderable, soft, three-stage acrylic heteropolymer having a calculated T.sub.g of about (-) 40.degree. to (=) 20.degree. C. which is suitable for producing films and sheets useful to coat textile materials and other substrates to form composites. The heteropolymer can be coagulated and then introduced into a calendering apparatus to produce films and sheets at substantially lower temperatures than are required for calendering vinyl halide polymers.
