摘要： The present invention relates to a grafted liquid polymer comprising a polymer of a C4 to C7 monoolefin monomer and a C4 to C14 multiolefin monomer, a grafting material and a free radical initiator and to a process for the preparation of the grafted liquid polymer. More specifically, a liquid maleated butyl rubber composition is disclosed. The present invention also relates to grafted liquid polymer compositions which are curable in the presence of multifunctional amines. The compositions of the invention are used in a variety of applications, including injection molded fuel cells gaskets, adhesives, sealants or as polyurethane substrates.

摘要： The present invention relates to the modification of butyl elastomers, particularly halobutyl elastomers, under solvent free conditions with a phase transfer catalyst, particularly tetrabutyammonium bromide or trioctylmethylammonium chloride, in the presence of an alkyl metal salt of an oxygen or sulfur-based nucleophile. Suitable nucleophiles for use in the present invention include metal salts of tert-butylacetic acid, stearic acid, benzoic acid, 4-(dimethylamino)benzoic acid, antrancene-9- carboxylic acid, linoleic acid or mixture thereof, which are prepared by neutralization with an appropriate hydroxide base.
