PURPOSE:To obtain the title composition excellent in the resistance to permeation by a fluorohydrocarbon gas, by mixing a chlorinated rubber with a polyamide resin. CONSTITUTION:100 pts.wt. chlorinated rubber (e.g., chloroprene rubber) is mixed with 11-400 pts.wt. polyamide resin and, optionally, carbon black, a white filler, a plasticizer, a crosslinking agent, a process aid, etc., and the obtained mixture is uniformly blended at a temperature higher than the m.p. of the polyamide resin. |
