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.
