| 摘要 |
This invention discloses a polymeric blend which is useful in manufacturing a wide variety of articles, said blend being comprised of (1) a thermoplastic polyurethane and (2) a rubbery polymer which is comprised of repeat units which are comprised of (a) butyl acrylate, (b) at least one member selected from the group consisting of methyl methacrylate, ethyl methacrylate, methyl acrylate and ethyl acrylate, (c) acrylonitrile, (d) styrene, (e) a surfactant selected from the group consisting of sulfonates and sulfate derivatives, (f) a dispersant selected from the group consisting of aromatic formaldehyde condensation products and polycarboxylates or optionally a half ester maleate soap and (g) a crosslinking agent. These blends can be utilized in a wide variety of applications, such as automotive door handles, buttons and knobs. For instance, such blends exhibit excellent characteristics for making buttons and knobs for radios, television sets and other electronic devices. Insulation for electrical cables can also be made by blending such rubbery polymers into thermoplastic polyurethanes.
