Polyester-hydrogenated nitrile rubber compositions.

摘要

The rubber blend comprises (a) a thermoplastic polyester resin; and (b) a hydrogenated nitrile rubber (HNBR); the rubber being (partially) crosslinked. Also claimed is a compsn. comprising 70-20 pts. wt. (a) from polyethylene terephthalate and/or polybutylene terephthalate (PBT); and 30-80 pts. wt. (b) having less than 5 mole % double bond unsaturation; the rubber having been fully crosslinked by dynamic vulcanisation.
