ABSTRACT:
This invention discloses a process for manufacturing an elastomeric article by liquid injection molding, said process comprising the steps of: (I) heating a curable composition comprised of (1) a liquid polymer comprised of repeat units that are derived from a conjugated diolefin monomer, wherein said liquid polymer has a weight average molecular weight which is within the range of 5,000 to 100,000, and wherein the liquid polymer is functionalized with an amine 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.
