Abstract
Process for obtaining elastomers based on modified synthetic polyesters, characterized by starting from a substantially linear anhydrous polyester, with a hydroxyl number comprised between 20 and 80, provided with non-free carboxylic groups, obtained by reaction between at least one aliphatic dicarboxylic acid or a hydroxycarboxylic acid optionally mixed with a small amount of an aromatic dicarboxylic acid, and with at least one polyhydric alcohol optionally mixed with a small amount of a polyfunctional amine or an aminoalcohol; whose polyester is reacted with a diisocyanate, in the proportion of 20-250% in excess of the equivalent to the free hydroxyl groups of said polyester; and the encoded polyester thus obtained is reacted with an amount at least equivalent to the free isocyanate groups, of water or of a non-polymeric polyfunctional compound which does not release formaldehyde and which has at least two reactive radicals selected from the group consisting of hydroxy and amino radicals.
