Abstract
PURPOSE: To produce sanitary rubber articles having excellent physical properties and chemical properties, by co-crosslinking a specific polymer and butyl rubber combined with divinylbenzene with the aid of an organic peroxide.
CONSTITUTION: There are mixed 30W75wt% of (A) a rubber prepared by combining divinylbenzene with a copolymer of isoprene rubber and isobutylene rubber, 10W30wt% of (B) at least one polymer selected from polybutadiene, styrene/ butadiene copolymer and PE and (C) white carbon having a particle diameter of 0.01W3μ, a specific surface area of 50W200m2/g and a pH of 6.0W10.5. The resulting mixture is co-crosslinked in the presence of an organic peroxide such as dicumyl peroxide or 2,5-dimethyl-2,5-di(t-butylperoxy)hexane.
EFFECT: It is possible to produce sanitary rubber articles having excellent elasticity and a low gas permeability and being useful as stoppers or seals of containers for medicines, foods, etc.
