Patent ID: 7351768

Claim:
A process for manufacturing an elastomeric article by liquid injection molding, said process comprising the steps of: (I) heating a curable composition which is comprised of (1) a liquid polymer which is comprised of repeat units that are derived a conjugated diolefin monomer and I-ethenyl-4-(3-butenyl)benzene, wherein said liquid polymer has a weight average molecular weight which is within the range of 5,000 to 100,000, wherein at least 50 weight percent of the repeat units in the liquid polymer are comprised of the conjugated diolefin monomer, wherein said liquid polymer has a vinyl microstructure content of at least 5 percent, and wherein the liquid polymer is functionalized with an ether moiety, (2) a carbonyl inhibited platinum catalyst, and (3) a tetrakis(dialkyl siloxy) silane crosslinking agent to a temperature which is within the range of 30° C. to 100° C.; (II) injecting the heated curable composition into a mold at a temperature which is within the range of 100° C. to 210° C. to produce the elastomeric article; and (III) removing the elastomeric article from the mold.
