AN IMPROVED WEATHER RESISTANT POLYESTERURETHANE COMPRISING THE REACTION PRODUCT OF ONE MOL EQUIVALENT OF AN ESSENTIALLY HYDROXYL TERMINATED SATURATED ALIPHATIC POLYESTER OF AN UNSUBSTITUTED DICARBOXYLIC ACID HAVING FROM 2 TO 10 CARBON ATOMS AND AN ALKYLENE DIOL HAVING FROM 2 TO 10 CARBON ATOMS, SAID POLYESTER HAVING A MOLECULAR WEIGHT OF BETWEEN ABOUT 500 AND 5,000, AN ACID NUMBER OF LESS THAN 10 AND A PLURALITY OF ESTER GROUPS IN THE MAIN POLYMER CHAIN, FROM ABOUT 1.0 TO 5.0 MOL EQUIVALENTS OF AN AROMATIC DIHYDROXYL COMPOUND SELECTED FROM THE CLASS CONSISTING OF 1,4-BIS(2-HYDROXY ETHOXY) BENZENE, 4,4''-BIS(2-HYDROXY ETHOXY)DIPHENYL DIMETHYL METHANE, 1,3-BIS(2-HYDROXY ETHOXY)BENZENE, 1,2,-BIS(2HYDROXY ETHOXY)BENZENE, 1,4-BIS(6-HYDROXY HEXOXY)BENZENE, 1,4-BIS(3-HYDROXY PROPOXY)BENZENE, AND 1,4-BIS(3HYDROXY BUTOXY)BENEZENE, AND FROM ABOUT 2.0 TO 6.0 MOL THE CLASS CONSISTING OF M-PHENYLENE DIISOCYANATE, P-PHENYLTHE CLASS CONSISTING OF M-PHENYLENE EIISOCYANATE, P-PHENYLENE DIISOCYANATE, TETRACHLORO M-PHENYLENE DIISOCYANATE, DURENE DIISOCYANATE, AND BITOLYLENE DISSOCYANATE, THE MOLAR AMOUNT OF SAID DIISOCYANATE BEING SUBSTANTIALLY EQUIVALENT TO THE MOLAR AMOUNT OF SAID POLYESTER OF SAID SAID AROMATIC DI-HYDROXYL COMPOUND COMBINED.
