Abstract:
A crosslinked film formed from a polymer latex composition, said polymer latex composition comprising:about 5 to about 65 weight percent of an aromatic vinyl monomer; about 35 to about 90 weight percent of a conjugated diene monomer; and about 0.5 to about 10 weight percent of a component selected from the group consisting of an unsaturated acid monomer, a partial ester of an unsaturated polycarboxylic acid monomer, and mixtures thereof; said polymer latex composition being devoid of natural rubber; wherein said crosslinked film has a degree of crosslinking such that the film has a tensile strength of at least about 1000 psi, an elongation of at least 400 percent, and a modulus at 100 percent elongation of no more than about 500 psi.
