    摘要: A solution of butyl rubber in an inert solution such as n-hexane is halogenated in a continuous process using bromine chloride vapor and high intensity mixing means for both the halogenation and subsequent neutralization steps. Adjustment of the mole ratio of bromine chloride to isoprene, where an isobutylene-isoprene butyl copolymer is used, to less than about 1.5 to 1 prevents overhalogenation and significant molecular weight loss, while the use of bromine chloride vapor results in improved process safety.The doubly halogenated product, containing both bromine and chlorine in its structure can be vulcanized in the absence of sulfur, e.g., with zinc oxide. It is particularly useful in rubber compositions where the singly halogenated product is employed, but demonstrates product performance advantages compared to both brominated butyl rubber and chlorinated butyl rubber.

    摘要: A stabilized halogenated butyl rubber composition comprises halogenated butyl rubber, an alkali metal or alkaline earth metal carboxylate, an ether and an oxide or hydroxide of a Group IIA metal as exemplified by halogenated butyl rubber containing both bromine and chlorine stabilized with a composition comprising calcium stearate, polyethoxylated adducts of sorbitol esterified with from 1 to 6 moles of oleic acid and mixtures thereof, and calcium hydroxide.Halogenated butyl rubbers stabilized in the manner disclosed exhibit improved resistance to discoloration upon high temperature exposure, such as during the drying of polymers in the course of manufacture.

    摘要: The present invention discloses a pad for use under a covering layer. The pad can include a mat with at least one off-all portion, the at least one off-all portion having a puzzle-piece shape. The mat has a bounding portion that is complementary shaped with at least part of the at least one off-all portion, and the bounding portion and the off-all portion have an interference fit therebetween. The interference fit between the bounding portion and the at least one off-all portion provides for the off-all portion to be removably attached to the mat. In addition, removal of the at least one off-all portion from the mat provides an opening for a component to be nested therewithin, while not removing the at least one off-all portion provides structural support to the covering layer that is located over the mat.
