| 摘要 |
The invention relates to thermoplastic polymer compositions containing a copolymer of a polysiloxane and an olefin polymer as a friction reducing additive in the thermoplastic polymer composition. The invention provides a polymer composition comprising a thermoplastic polymer (A) selected from a polyacetal and a polyolefin, and a copolymer (B) of a polysiloxane (B1) and an olefin polymer (B2), characterised in that the copolymer (B) is a branched block copolymer and is free of any siloxane homopolymer. |
