Abstract: A curable liquid rubber composition including at least one liquid polyene component and at least one heat activated crosslinking agent. The liquid polyene component may be a single polyene or a blend of polyenes. In one embodiment, the liquid polyene component may contain on a molar basis, at least one monomer that results in at least 45 molar percent of C2-C13 pendant groups. In another embodiment, the liquid polyene component may contain on a molar basis at least one monomer that results in at least 20 molar percent of C2-C5 pendant groups, and at least one monomer that results in at least 7 molar percent of C6-C13 pendant groups. After curing, the liquid rubber composition may have a loss factor greater than 0.51, a maximum loss factor temperature greater than −10° C., and a swelling ratio in toluene from 40% to 170% by weight.

Abstract: A curable liquid rubber composition having improved viscosity stability is provided. The curable liquid rubber composition includes at least one functionalized crosslinkable polymer that is liquid at 25° C., contains at least one diene monomer in polymerized form, and is functionalized with one or more anhydride functional groups, one or more hydroxyl functional groups or one or more (meth)acrylate functional groups; at least one non-functionalized crosslinkable polymer that is liquid at 25° C., contains at least one diene monomer in polymerized form, and is not functionalized with anhydride, hydroxyl or (meth)acrylate functional groups; at least one metallic monomer coagent which is a metal carboxylate salt containing at least one (meth)acrylate functional group; and at least one inorganic filler. The curable liquid rubber composition has a total moisture content of not more than 1000 ppm, whereby controlling the amount of water reduces the tendency of the composition to exhibit an increase in viscosity over time.

Abstract: A curable low sulfur liquid rubber composition including at least one polymer which contains, in polymerized form, at least one monomer having a carbon chain of four and a peroxide system which includes at least one organic peroxide and at least one coagent. The polymer has a vinyl content of 1% to 90% and a number average molecular weight of 800 g/mol to 70,000 g/mol. The curable low sulfur liquid rubber composition has a sulfur content of 0 to 1%, by weight, and is curable at a temperature of 100° C. to 190° C.
