Pigmented thermoplastic resins |
摘要 |
A polymer blend comprises from about 60 parts to about 99.9 parts by weight of a pigmented thermoplastic resin, which resin is a polyester or a polycarbonate or mixtures thereof, and from about 0.1 part to about 40 parts of a sequentially produced multi-stage polymer. The multi-stage polymer comprises a polymer core of at least about 10 parts, based on the weight of the multi-stage polymer. The core is polymerized from a styrenic monomer, or a mixture of styrenic monomers. The styrenic monomer of the core comprises at least about 50% by weight of said core. A second monomer may be present and a crosslinking monomer for styrene is present in said core. The second stage of the multi-stage polymer comprises a polymeric soft stage and the outer stage of the multi-stage polymer is a rigid thermoplastic.
