Abstract

The instant invention provides to polymeric blend formulation, and a multilayer structure comprising a skin layer derived from the polymeric blend formulation, and method of making the same. The polymeric blend formulation comprises: (a) 40 to 65 percent by weight of an ethylene-based copolymer composition; (b) 15 to 40 percent by weight of a chlorinated olefin polymer composition; (c) from 0.1 to 25 percent by weight of a filler; (d) 10 to 30 weight percent by weight of an adhesion promoting agent; and (e) optionally, 1 to 4 percent by weight of a mineral oil.

First claim

I claim:

1. A polymeric blend formulation consisting of:
(a) 40 to 65 percent by weight of an elastomeric ethylene copolymer;
(b) 15 to 40 percent by weight of a chlorinated olefin polymer;
(c) 0.1 to 25 percent by weight of a filler;
(d) 10 to 30 percent by weight of an adhesion promoting agent;
(e) optionally, 1 to 4 percent by weight of a mineral oil;
and at least one additive selected from a stabilizing agent, a processing aid, a pigment, a plasticizer, or any combination thereof.

2. The polymeric blend formulation according to claim 1 , wherein said filler is calcium carbonate or said adhesion promoting agent is maleic anhydride grafted polyolefin copolymer.

3. A process for producing a polymeric blend formulation of claim 1 , and comprising the steps of:
providing an elastomeric ethylene copolymer, wherein said elastomeric ethylene copolymer consists of from 40 to 60 percent by weight based on the weight of the polymeric blend formulation;
providing a chlorinated olefin polymer composition, wherein said chlorinated olefin polymer composition consists of from 25 to 40 percent by weight based on the weight of the polymeric blend formulation;
providing a filler, wherein said filler consists of from 0.1 to less than 25 percent by weight based on the weight of the polymeric blend formulation; providing an adhesion promoting agent, wherein said adhesion promoting agent consists of from 10 to 30 percent by weight based on the weight of the polymeric blend formulation;
optionally, providing a mineral oil, wherein said mineral oil consists of 1 to 4 percent based on the weight of the polymeric blend formulation;
melt blending said ethylene-based copolymer composition, said chlorinated olefin polymer composition, said filler, said adhesion promoting agent, and said optional mineral oil; and thereby producing said polymeric blend formulation.

4. A multilayer structure comprising
a skin layer comprising a sheet derived from a polymeric blend formulation consisting of: (a) 40 to 65 percent by weight of an elastomeric ethylene copolymer; (b) 15 to 40 percent by weight of a chlorinated olefin polymer; (c) from 0.1 to 25 percent by weight of a filler; (d) 10 to 30 percent by weight of an adhesion promoting agent; (e) optionally, 1 to 4 percent by weight a of mineral oil; and at least one additive selected from a stabilizing agent, a processing aid, a pigment, a plasticizer, or any combination thereof;
optionally, an inner layer derived from an aqueous dispersion; and a substrate layer, wherein said inner layer is disposed there between said skin layer and said substrate layer.

5. A method for making the multilayer structure of claim 4 said method comprising the steps of laminating a sheet derived from a polymeric blend formulation consisting of (a) 40 to 65 percent by weight of an elastomeric ethylene copolymer; (b) 15 to 40 percent by weight of a chlorinated olefin polymer composition; (c) from 0.1 to 25 percent by weight of a filler; (d) 10 to 30 percent by weight of an adhesion promoting agent; (e) optionally, 1 to 4 percent by weight of a mineral oil; and at least one additive selected from a stabilizing agent, a processing aid, a pigment, a plasticizer, or any combination thereof, to a substrate, optionally, in the presence of an aqueous dispersion on at least one surface of said substrate; and thereby forming said multilayer structure comprising said skin layer, optionally, an inner layer derived from said aqueous dispersion; and said substrate layer.
