    摘要: POLYMERIZABLE COMPOSITION COMPRISING AN ADDITION PRODUCT AND AN ETHYLENICALLY UNSATURATED MONOMER OF LESS THAN 300 PARTS BY WEIGHT PER 100 PARTS BY WEIGHT OF SAID ADDITION PRODUCT; SAID ADDITION PRODUCT BEING PREPARED BY INTRODUCING POLYMERIZABLE UNSATURATED GROUPS OF A DERIVATIVE OF ACRYLAMIDE THROUGH THE ETHER EXCHANGE REACTION TO A COMPOUND HAVING AT LEAST TWO HYDROXYL GROUPS IN THE MOLECULE AND HAVING A HYDROXYL EQUIVALENT OF 30 TO 240 AND/OR A SYNTHETIC RESIN HAVING MORE THAN TWO HYDROXYL GROUPS IN THE SKELETON, HAVING A HYDROXYL EQUIVALENT OF 130 TO 3000 AND HAVING A NUMBER AVERAGE MOLECULAR WEIGHT OF 500 TO 100,000, AND SAID DERIVATIVES OF ACRYLAMIDE CORRESPONDING TO THE GENERAL FORMULA:

    CH2=C(-R1)-CO-NH-CH2-O-R2

    IN WHICH R1 IS HYDROGEN OR METHYL GROUP AND R2 IS HYDROGEN OR ALKYL GROUP OF 1 TO 8 CARBON ATOMS.

    摘要: An oil modified unsaturated polyester resin in which at least one hydroxyl group is left at a terminal of its molecule, having a number average molecular weight of from about 1,000 to about 4,000 and acid value of from 5 to 60 is made to react with at least one diisocyanate compound having from 0.2 to 1.2 equivalent of isocyanato group with respect to 1 equivalent of hydroxyl group of said unsaturated polyester resin to produce an urethanated unsaturated polyester resin having a molecular weight of from about 2,000 to about 20,000.
