an unsaturated polyester resin,
B. a cross-linking monomer,
C. a low profile additive,
D. a reinforcing fiber, and
E. a silicon-oxyalkylene copolymer flow
control
agent and surface modifying agent.
Atkins lists the advantages of his inventive molding
composition as follows (Atkins, p. 3, l. 50-55):
n improve flow during molding,
n improved physicals for the molded product,
n smoother surfaces for the molded product, i.e., better
replication of the mold and the mold's dimensions; and
n molded fiber reinforced plastic parts that have less
shrinkage.
We find that the molding composition Atkins describes
differs from the molding composition appellants claim in the
polysiloxane copolymer component. Appellants’ thermoset
molding composition requires a polysiloxane polyalkylene
copolymer surface modifying agent. Atkins’ thermoset molding
composition requires a polysiloxane polyalkyleneoxyalkylene
surface modifying agent.
