Claim 3

The process of claim 1 wherein (B) is a copolymer of ethylene and vinyl acetate and (b) is ethyl acrylate.

Claim 4

A process which comprises charging to a glass casting cell and casting the partial interpolymerization product of (A) from about 25 percent to about 99 percent, by weight, of (a) at least 50 percent, by weight, of methyl methacrylate, (b) up to 50 percent, by weight, of a comonomer selected from the group consisting of an alkyl acrylate and vinyl acetate and (c) up to 20 percent, by weight, based on the total weight of (a), (b) and (c) of another monomer copolymerizable with said (a), and (B) from about 1 percent to about 75 percent, by weight, of a copolymer of (1) from about 50 percent to about 95 percent, by weight, of ethylene, (2) a comonomer selected from the group consisting of vinyl acetate, alkyl acrylates and methacrylates, said alkyl groups having from 1-18 carbon atoms, inclusive, acrylic acid, methacrylic acid and mixtures thereof, and (3) up to 20 percent, by weight, based on the total weight of (1), (2) and (3), of another monomer copolymerizable with said (1), and in the presence of a free-radical generating catalyst and in the absence of water.

Claim 5

A composition of matter comprising (A) from about 25 percent to about 99 percent, by weight, of a polymer of (a) at least 50 percent, by weight, of methyl methacrylate, (b) up to 50 percent, by weight, of a comonomer selected from the group consisting of an alkyl acrylate and vinyl acetate and (c) up to 20 percent, by weight, based on the total weight of (a), (b) and (c) of another monomer copolymerizable with said (a) and (B) from about 1 percent to about 75 percent of a, cross-linked polymer of (1) from about 50 percent to about 95 percent, by weight, of ethylene, (2) a comonomer selected from the group consisting of vinyl acetate, alkyl acrylates and methacrylates, said alkyl groups having from 1-18 carbon atoms, inclusive, acrylic acid, methacrylic acid and mixtures thereof and (3) up to 20 percent, by weight, based on the total weight of (1), (2) and (3) of another monomer copolymerizable with said (1), said (B) having grafted thereon the monomers of said (A).

Claim 6

The process which comprises interpolymerizing (A) from about 25 percent to about 99 percent, by weight, of (a) at least 50 percent, by weight, of methyl methacrylate, (b) up to 50 percent, by weight, of a comonomer selected from the group consisting of an alkyl acrylate and vinyl acetate and (c) up to 20 percent, by weight, based on the total weight of (a), (b) and (c) of another monomer copolymerizable with said (a) in the presence of (B) from about 1 percent to about 75 percent, by weight, of a cross-linked copolymer of (1) from about 50 percent to about 95 percent, by weight, of ethylene, (2) a comonomer selected from the group consisting of vinylacetate, alkyl acrylates and methacrylates, said alkyl groups having from 1-18 carbon atoms, inclusive, acrylic acid, methacrylic acid and mixtures thereof, and (3) up to 20 percent, by weight, based on the total weight of (1), (2) and (3), of another monomer copolymerizable with said (1), in the presence of a free-radical generating catalyst and a solvent for said (A) and said (B), at a temperature ranging from about 10* C. to about 150* C. and in the absence of water.
