Abstract
Partially crosslinked thermoplastic elastomer which is produced as follows: PA1 (A) propylene (10-90 weight part), (B) halogenated butyl rubber (90-10 weight part, (A)+(B)=100 weight part), (C) olefinic rubber (10-120 weight part) and (D) mineral oil softening agent (5-120 weight part) are heated in the presence of (E) metal oxide and/or metal chloride. To the composition based on (A)-(E) (100 weight part), (F) polyolefin (300-1900 weight part) and (G) styrenic rubber (50-1100 weight part) are blended. The composition has particularly good moldability, compatibility, low temperature impact strength, and gloss, and can be used for large scale molding.
