Abstract:
1. A prepolymer composition comprising in weight percent: a) from 20 to less than 50% of at least one oligomer, wherein said oligomer has a number average molecular weight in the range of 500 to 50,000; wherein a polymer formed from said oligomer has a glass transition temperature equal to or less than −20° C., and wherein said at least one oligomer is selected from the group consisting of: b) from greater than 50% to 70% of a least one tackifying resin, wherein said tackifying resin has a number average molecular weight less than or equal to 1500 and a softening point in the range of 65 to 150° C.; and c) from 0 to 30% of at least one monomer selected from the group consisting of C
