Abstract:
A polymer composition suitable for use as a capstock composition comprising a blend of:a melt extrudable acrylic polymer component which comprises more than 50% by weight, based on the weight of the acrylic polymer component, of a high molecular weight acrylic polymer having a molecular weight in the range of from about 150,000 to about 350,000, on a number average basis, and up to 50% by weight, based on the weight of the acrylic polymer component, of a low molecular weight acrylic polymer having a molecular weight of from about 10,000 to about 100,000, on a number average basis; from 10% to 50% by weight of the composition of a halogen donor component; an effective amount of a halogen volatilisation agent; and a char-inducing component which induces formation of a char upon application of flame to the composition.
