The present invention relates to a novel acrylic composition, novel acrylic castings prepared therefrom, and a novel process for the preparation of the acrylic castings. The composition comprises methyl methacrylate, about 0.5 to 20% by weight of a carboxylated cellulose ester, and about 1 to 100 pp
The present invention relates to a novel acrylic composition, novel acrylic castings prepared therefrom, and a novel process for the preparation of the acrylic castings. The composition comprises methyl methacrylate, about 0.5 to 20% by weight of a carboxylated cellulose ester, and about 1 to 100 ppm of a vanadium promoter. Optionally, a heat dissipative material, such as a plasticizer or an additional monomer, can also be employed. In accordance with the process of the present invention, an acrylic monomer comprising methyl methacrylate is combined with about 0.5 to 20% by weight of a carboxylated cellulose ester so as to form an easily pourable syrup, about 1 to 100 ppm of a vanadium promoter is added to the syrup and the resulting solution is poured into a suitable mold, and the solution is cured at room temperature so as to form a hard acrylic casting.

A novel acrylic composition which comprises about 60 to 99 percent by weight methyl methacrylate, about 0.5 to 20 percent by weight of a carboxylated cellulose ester having an acid number of at least about 5, an inherent viscosity of from about 0.01 to about 1.00 and wherein the anhydroglucose units
A novel acrylic composition which comprises about 60 to 99 percent by weight methyl methacrylate, about 0.5 to 20 percent by weight of a carboxylated cellulose ester having an acid number of at least about 5, an inherent viscosity of from about 0.01 to about 1.00 and wherein the anhydroglucose units thereof have ring substituents comprising by weight based on total polymer weight, of from about 0.05 to about 20% hydroxyl groups, from about 0.5 to about 44% acetyl groups, from 0 to about 54% butyryl groups, from 0 to about 47% propionyl groups, from about 0.4 to about 4.0% total carboxyl groups wherein from about 20% to about 100% of these carboxyl groups are non-saponifiable backbone, and wherein the material has a lactone level of from about 4.52×10-5 to about 6.13×10-4, and about 1 to 100 ppm of a vanadium promoter. A novel acrylic composition which comprises (i) about 60 to 99 percent by weight of an acrylic monomer consisting essentially of methyl methacrylate, (ii) about 0.5 to 20 percent by weight of a carboxylated cellulose ester comprising carboxylated cellulose acetate, carboxylated cellulose acetate propionate, carboxylated cellulose acetate butyrate, or a mixture thereof, said carboxylated cellulose ester having an acid number of at least about 5, an inherent viscosity of from about 0.01 to about 1.00 and wherein the anhydroglucose units thereof have ring substituents comprising by weight based on total polymer weight, of from about 0.05 to about 20% hydroxyl groups, from about 0.5 to about 44% acetyl groups, from 0 to about 54% butyryl groups, from 0 to about 47% propionyl groups, from about 0.4 to about 4.0% total carboxyl groups wherein from about 20% to about 100% of these carboxyl groups are non-saponifiable backbone, and wherein the material has a lactone level of from about 4.52×10 -5 to about 6.13×10-4, (iii) about 1 to 100 ppm of a vanadium promoter comprising vanadium naphthenate, and (iv) up to about 20 percent by weight of a heat dissipative material.
