POLYESTER URETHANE-CONTAINING RESIN BLENDS, MOULDING COMPOSITIONS AND PRODUCTS THEREOF |
摘要 |
<p>Polyester urethane derivatives having the following general formula: c-i-(d-n)td-i-c wherein d is a radical derived from an organic polyol; n is a radical derived from an unsaturated aliphatic dicarboxylic acid or an anhydride thereof; i is a radical derived from a polyisocyanate; c is a carbamyl-linked radical derived from a hydroxy-terminated ester of acrylic or methacrylic acid; t is an integer equal to from 1 to about 5; in ethylenically unsaturated monomer solutions are thickened to moldable non-sticky gels by the formation in said solution of minor amounts of branch chain polyurethane resin mixtures free of ethylenic unsaturation. The physical properties of reinforced molded articles made from these molding compositions show dramatic improvement in impact strength and flexibility.</p> |
