Alkyd resins made from a polymerized alcohol and method of preparation

Claim 1

A METHOD OF PREPARING A RESIN COMPRISING THE STEPS OF (1) PARTIALLY ESTERIFYING (A) A POLYMER OF AN ALCOHOL HAVING ETHYLENIC UNSATURATION BETWEEN TWO CARBON ATOMS IN AN ALIPHATIC GROUPING, ONE OF WHICH CARBON ATOMS IS DIRECTLY LINKED TO A SATURATED CARBINOL CARBON ATOM, SAID POLYMER CONTAINING AN AVERAGE NUMBER OF -CH2OH GROUPS PER MOLECULE OF FROM THREE TO TEN, WITH (B) A MEMBER SELECTED FROM THE GROUP CONSISTING OF SATURATED, ETHYLENICALLY UNSATURATED, AND AROMATIC MONOCARBOXYLIC ACIDS CONTAINING MORE THAN ONE CARBON ATOM, AND ANHYDRIDES THEREOF, AND (2) COMPLETING THE ESTERIFICATION REACTION AT A TEMPERATURE WITHIN THE RANGE OF 150* C. TO 250* C. BY REACTING, UNTIL A COMPOSITION HAVING AN ACID NUMBER OF FROM 5 TO ABOUT 160 HAS BEEN OBTAINED, THE PRODUCT OF PARTIAL ESTERIFICATION OF (A) AND (B) WITH (C) A MEMBER SELECTED FROM THE GROUP CONSISTING OF SATURATED, ETHYLENICALLY UNSATURATED, AND AROMATIC POLYCARBOXYLIC ACIDS CONTAINING MORE THAN TWO CARBON ATOMS, AND ANHYDRIDES THEREOF, SAID INGREDIENTS OF (B) AND (C) BEING EMPLOYED IN AN AMOUNT CORRESPONDING TO FROM ABOUT 10 TO ABOUT 70 MOL PER CENT OF THE LATTER TO FROM ABOUT 90 TO ABOUT 30 MOL PER CENT OF THE FORMER, AND THE INGREDIENT OF (A) BEING EMPLOYED IN AN AMOUNT CORRESPONDING TO FROM ABOUT 3 TO 30% IN EXCESS OF THAT REQUIRED FOR COMPLETE ESTERIFICATION OF THE INGREDIENTS OF (B) AND (C) AND CONSTITUTING AT LEAST 30% OF THE TOTAL POLYHYDRIC ALCOHOL REACTANT.

Claim 2

A METHOD OF PREPARING A RESIN COMPRISING THE STEPS OF (1) PARTIALLY ESTERIFYING (A) A POLYMER OF AN ALCOHOL HAVING ETHYLENIC UNSATURATION BETWEEN TWO CARBON ATOMS IN AN ALIPHATIC GROUPING, ONE OF WHICH CARBON ATOMS IS DIRECTLY LINKED TO A SATURATED CARBINOL CARBON ATOM, SAID POLYMER CONTAINING AN AVERAGE NUMBER OF -CH2OH GROUPS PER MOLECULE OF FROM THREE TO TEN, WITH (B) A MEMBER SELECTED FROM THE GROUP CONSISTING OF SATURATED, ETHYLENICALLY UNSATURATED, AND AROMATIC MONOCARBOXYLIC ACIDS CONTAINING MORE THAN ONE CARBON ATOM, AND ANHYDRIDES THEREOF, AND (2) COMPLETING THE ESTERIFICATION REACTION AT A TEMPERATURE WITHIN THE RANGE OF 150* C. TO 250* C. BY REACTING, UNTIL A COMPOSITION HAVING AN ACID NUMBER OF FROM 5 TO ABOUT 160 HAS BEEN OBTAINED, THE PRODUCT OF PARTIAL ESTERIFICATION OF (A) AND (B) WITH (C) A MEMBER SELECTED FROM THE GROUP CONSISTING OF SATURATED, ETHYLENICALLY UNSATURATED, AND AROMATIC POLYCARBOXYLIC ACIDS CONTAINING MORE THAN TWO CARBON ATOMS, AND ANHYDRIDES THEREOF, SAID INGREDIENTS OF (B) AND (C) BEING EMPLOYED IN AN AMOUNT CORRESPONDING TO FROM ABOUT 10 TO ABOUT 70 MOL PER CENT OF THE LATTER TO FROM ABOUT 90 TO ABOUT 30 MOL PER CENT OF THE FORMER, AND THE INGREDIENT OF (A) BEING EMPLOYED IN AN AMOUNT CORRESPONDING TO FROM ABOUT 3 TO 30% IN EXCESS OF THAT REQUIRED FOR COMPLETE ESTERIFICATION OF THE INGREDIENTS OF (B) AND (C) AND CONSTITUTING AT LEAST 30% OF THE TOTAL POLYHYDRIC ALCOHOL REACTANT.
