Inorganic/organic-filled styrenic thermoplastic door skins
First Claim
1. A multilayered, substantially planar skin for securing to an article exposed to various environmental conditions, said skin comprising:
- a first layer exposed to the environmental conditions and substantially free of organic and/or inorganic fillers and comprising a copolymer of at least one ethylenically unsaturated monomer, at least one aromatic vinyl compound, and at least one acrylic ester elastomer; and
a second layer shielded from the environmental conditions by said first layer and comprising a terpolymer of at least one ethylenically unsaturated monomer, at least one butadiene, and at least one aromatic vinyl compound and having at least one filler dispersed therein in an amount of from about 5 to about 35 percent based on a total weight of said second layer for providing increased resistance.

Abstract
An article comprising a frame having an outer periphery with a multilayered, substantially planar skin secured thereto that is exposed to various environmental conditions is disclosed. The skin comprises a first layer exposed to the environmental conditions and a second layer shielded from the environmental conditions by the first layer. The first layer is substantially free of organic and/or inorganic fillers and comprises a copolymer of at least one ethylenically unsaturated monomer, at least one aromatic vinyl compound, and at least one acrylic ester elastomer. The second layer comprises a terpolymer of at least one ethylenically unsaturated monomer, at least one butadiene, and at least one aromatic vinyl compound and has at least one filler is dispersed therein in an amount of from about 5 to about 35 percent based on a total weight of the second layer.

21. An article exposed to various environmental conditions, said outdoor article comprising:
-
a frame having an outer periphery;
at least one multilayered, substantially planar skin secured to said frame and comprising a first layer exposed to the environmental conditions disposed on top of a second layer shielded from the environmental conditionals by said first layer;
said first layer substantially free of organic and/or inorganic fillers comprising a copolymer of at least one ethylenically unsaturated monomer, at least one aromatic vinyl compound, and at least one acrylic ester elastomer;
