Patent ID: 7335788

Claim:
A composition, comprising a free radically polymerizable monomer selected from a conjugated diene monomer, a vinyl monomer and combinations thereof and a dithiocarbainate compound having the formula: wherein j is 1 or 2; wherein R 12 and R 13 , independently, are the same or different, are optionally substituted, and are a linear or branched alkyl having from 1 to about 12 carbon atoms; or an aryl group having from 6 to about 18 carbon atoms; or R 12 and R 13 can form and be part of a substituted or unsubstituted cyclic ring having from 3 to about 12 carbon atoms, wherein said substituted groups above are independently selected from alkyl having from 1 to 6 carbon atoms; an aryl group; a halogen; a cyano group; an ether having a total of from 2 to about 20 carbon atoms; a nitro; and combinations thereof; with the proviso that when j is 1, T is (—NR 15 R 16 ), and when j is 2, T is a divalent radical having a nitrogen atom directly connected to each carbon atom of the two thiocarbonyl groups; and wherein R 15 and R 16 independently, are the same or different, optionally substituted, and is hydrogen; or a linear or branched alkyl having from 1 to about 18 carbons; or an aryl group or an aryl alkyl group having from 6 to about 18 carbon atoms, optionally saturated or unsaturated; or an arylalkyl having from 7 to about 18 carbons; or an alkenealkyl having from 3 to about 18 carbon atoms; or polyalkylene glycol ether; or an amine; or R 15 and R 16 are in the form of a substituted or unsubstituted cyclic ring with the nitrogen atom having a total of 4 to about 12 carbon atoms; wherein when optionally substituted said R 15 and R 16 groups are substituted with a substituent selected from an alkyl having from 1 to 6 carbon atoms; an aryl; a halogen; a cyano group; an amino group; an alkene group; an alkoxycarbonyl group; an aryloxycarbonyl group; a carboxy group; an acyloxy group; a carbamoyl group; an alkylcarbonyl group; an alkylarylcarbonyl group; an arylcarbonyl group; an arylalkylcarbonyl group; a phthalimido group; a maleimido group; a succinimido group; amidino group; guanidimo group; allyl group; epoxy group; alkoxy group; an alkali metal salt; a quaternary ammonium salt; a hydroxyl group; an ether having a total of from 2 to about 20 carbon atoms; a nitro group; a sulfur group; phosphorous group a carboalkoxy group; and combinations thereof.
