Pigmented thermoplastic resin compositions. |
摘要 |
<p>Impact resistance can be imparted to pigmented polyesters and/or polycarbonates without imparting unacceptable non-uniformity in colour appearance during moulding in polymer compositions comprising; (a) a polymer core comprising at least 10 percent of the weight of the multi-stage polymer, said core comprising styrenic monomer, crosslinking monomer and, optionally, non-styrenic non-crosslinking monomer, the units of styrenic monomer making up at least 50 percent by weight of the core weight. (b) polymeric soft stage immediately subsequent to said core; and (c) a rigid thermoplastic outer stage.</p> |
