ACRYLONITRILE POLYMERS STABILISED AGAINST THERMAL DISCOLORATION BY THE PRESENCE OF NITROALKANES |
摘要 |
<p>The Specification describes polymer materials comprising (a) a homopolymer of acrylonitrile or a copolymer of acrylonitrile and at least one further copolymerisable monomer, the copolymer containing at least 20% by weight of units of acrylonitrile; and (b) at least one nitroalkane in an amount sufficient to inhibit or prevent thermal discoloration. The anti-discoloration additive can be incorporated into a monomer composition from which the homopolymer or copolymer is formed or can be admixed with the formed polymer.</p> |
