Abstract
PURPOSE: To crosslink easily polychloroprene at ordinary temperature under normal pressure by a method wherein polychloroprene is modified to produce a crosslinkable silane-grafted polymer which is then contacted with water in the presence of a silanol condensation catalyst.
CONSTITUTION: 0.1W20pts.wt. Amino-organosilane [e.g. H2NC3H6Si (OC2H5)3] is added to 100pts.wt. polychloroprene. The mixture is kneaded at 100°C or lower to form a silane-grafted polymer of polychloroprene. This product is molded into a desired shape, and then contacted with water in the presence of 0.01W10pts.wt. silanol condensation catalyst (e.g. dibutyltin dilaurate) per 100pts.wt. grafted polymer for curing. A mercapto-organosilane may be used in place of said amino- organosilane.
