Abstract
The present invention relates to an antistatic polymer composition and more specifically to a composition comprising a thermoplastic polymer (A) and a copolymer (B) comprising polyamide blocks and polyether blocks comprising essentially ethylene oxide units —(C2H4—O)—, the copolymer (B) having a melting temperature of between 80 and 150° C. It is of use for the polymers (A) which are heat-sensitive or which are processed at low temperature.

An antistatic polymer composition comprising a thermoplastic polymer (A) and a copolymer (B) comprising polyamide blocks and polyether blocks comprising ethylene oxide units —(C2H4—O)—, the copolymer (B) having a melting temperature of between 80 and 150° C.
An antistatic polymer composition comprising as the sole polymers:
- a thermoplastic polymer (A) and a copolymer (B) comprising polyamide blocks and polyether blocks comprising ethylene oxide units —(C2H4—O)—, the copolymer (B) having a melting temperature of between 80 and 150° C.
A method of providing an antistatic property for a heat-sensitive thermoplastic polymer (A) comprising admixing with said thermoplastic polymer a copolymer (B) comprising polyamide blocks and polyether blocks comprising ethylene oxide units —(C2H4—O)—, the copolymer (B) having a melting temperature of between 80 and 150° C.
