We reverse.
The subject matter on appeal is directed to a
gasketing compound (composition) comprising a first vinyl
chloride resin, a second vinyl chloride resin, and an external
plasticizer. The first vinyl chloride resin has a high gel
content, and an inherent viscosity greater than about 1.02,
and a porosity greater than about .34 cc/gm. The second vinyl
chloride resin has a low gel content, an inherent viscosity of
at least about 1.02, and a porosity of at least about .34
cc/gm. When the composition is molded into a gasket, the
molded article exhibits low plasticizer migration and a low
marring effect on a painted surface.
Like the claimed invention, Matsumoto discloses a
composition comprising a first vinyl chloride polymer, a
