Abstract: POLYURETHANES AND A PROCESS FOR PREPARING THEM IN WHICH POLYISOCYANATES ARE REACTED WITH ALIPHATIC POLYCARBONATES CONTAINING AT LEAST TWO HYDROXYL GROUPS AND HAVING A MOLECULAR WEIGHT OF 800 TO 3000, WHICH POLYCARBONATES HAVE BEEN PREPARED BY POLYMERIZING UNSATURATED COMPOUNDS IN SITU, IF DESIRED WITH FORMATION OF GRAFT POLYMERS. THE HYDROLYTICALLY STABLE POLYURETHANES OF THIS INVENTION ARE HIGHLY ADVANTAGEOUS FOR USE IN ANY APPLICATION IN WHICH HYDROLYTIC ONDITIONS MAY BE ENCOUNTERED SUCH AS, FOR EXAMPLE, BATHTUB MATS, KITCHEN AIDS, GEARS, MOLDED PARTS, GASKETS, O-RINGS, SHOE HEELS, SHOCK ABSORBERS AND SO ON.
