SILICON RUBBER, GASKET FOR FUEL CELL COMPRISING THE SAME, AND METHOD OF PREPARING THE SAME

摘要

A silicone rubber, and a method for preparing the silicone rubber are provided to improve gas barrier property, to reduce moisture penetration and to decrease compression set. A silicone rubber comprises a crosslinked product of an organic polysiloxane represented by the formula 1 and a silane compound represented by R3_(4-m) SiR4_m, wherein X is a halogen atom, a hydroxyl group, a C1-C5 alkoxy group, an ester group or a carboxylic acid group; R1 and R2 are a C1-C10 alkyl group, a C6-C20 arylene group or a C6-C20 alkylarylene group; R3 and R4 are independently a hydroxyl group or a C1-C5 alkoxy group; n is an integer of 10-10,000; and m is an integer of 0-4.
