Appeal No. 2001-0742
Application 09/128,912
Claims 8 and 17 are representative of the subject
matter on appeal and are reproduced below:
8. 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 1000 psi, an elongation of at least 400 percent, and a
modulus at 100 percent elongation of no more than about 500 psi.
17. A glove comprising a crosslinked film formed from
a polymer latex composition, the polymer latex composition com-
prising 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, the polymer latex composition
being devoid of natural rubber; wherein said film has a degree of
crosslinking such that said glove 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.
