Patent ID: 8022155

Claim:
A method for producing a polymerizate, said method comprising: A) preparing a polymerization-curable composition by mixing 10 to 80% by weight of component a) with 10 to 50% by weight of component b) wherein component a) is a reactive diluent based on acrylic acid or methacrylic acid derivatives, and component b) is a liquid gelatin hydrolysate or a gelatin hydrolysate soluble in the reactive diluent, said liquid gelatin hydrolysate or gelatin hydrolysate soluble in the reactive diluent substituted with a radical of the formula wherein R 2 is H or —CH 3 ; Z 1 is —O—(CH 2 ) x —CO—, —O—(CH 2 —CH 2 —O) x —CH 2 —CO—, —O—(CH 2 —CH 2 —O) x —CO—CH 2 —CH 2 —, —O—(CH 2 —CH 2 —O) x —OC—CH═CH—CO—, —O—CH 2 —CH(OH)—CH 2 —, or —O—(CH 2 —CH 2 —O) x —CH 2 —CH(OH)—CH 2 —; Z 2 is —O—(CH 2 ) X —O—, —O—(CH 2 —CH 2 —O) x —, —O—CH 2 —CH(OH)—CH 2 —O—, or —O—CH 2 —CH(OH)—CH 2 —O—(CH 2 —CH 2 —O) x —; x is 1 to 20; said liquid gelatin hydrolysate or gelatin hydrolysate soluble in the reactive diluent having a molecular weight of up to 10,000 Da; and B) polymerizing the polymerization-curable composition, in a mold or in layers, into a polymerizate having an E-modulus of more than 1,000 MPa.
