Abstract
A polyether imide resin composition is proposed which has improved ductility and is less harmful to mating parts during sliding and thus can be used as the material for parts requiring rub resistance and abrasion resistance. It comprises 50-99.5 percent by weight of a polyether imide and 50-0.5 percent by weight of a vulcanizable organopolysiloxane elastomer.
Claims5
A polyether imide resin composition comprising 50 to 0.5 percent by weight of a vulcanizable organopolysiloxane elastomer added to 50 to 99.5 percent by weight of a polyether imide which is a thermoplastic polymer having ether bonds and imide bonds.
