Reacting siloxane with glycerinedicarboxylic acid ester and thereafter with dicarboxylic acid

Claim 1

A METHOD OF PREPARING THERMOSETTING RESINOUS MATERIALS WHICH COMPRISES REACTING A RESSILOXANE CONTAINING FROM 0.9 TO 2.1 SILICON-BONDED MONOVALENT HYDROCARBON RADICALS PER SILICON ATOM, SAID RADICALS BEING SELECTED FROM THE GROUP CONSISTING OF SATURATED ALIPHATIC RADICALS OF LESS THAN SEVEN CARBON ATOMS, AND MONOCYCLIC ARYL RADICALS AND FROM .05 TO 2 SILICON-BONDED SILOXANE FUNCTIONAL GROUPOS PER SILICON ATOM, SAID GROUPS BEING SELECTED FROM THE GROUP CONSISTING OF ALKOXY AND ACYLOXY RADICALS, SAID ACYLOXY RADICALS BEING OF THE FORMULA RCOO- WHERE R IS A HYDROCARBON RADICAL, THE REMAINDER OF THE VLENCES OF THE SILICON BEING SATIFIED WITH OXYGEN ATOMS, WITH A GLYCEROL ESTER FORMED BY REACTING GLYCERINE WITH AN ACIDIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF DICARBOXYLIC ACIDS AND ANHYDRIDES THEREOF IN AMOUNT SCUH THAT THE RATIO OF GLYCERINE OH TO DICARBOXYLIC ACID GROUPS IS FROM 2.25:1 TO 3:1, SAID POLYSILOXANE AND SAID GLYCEROL ESTER BEING REACTED IN AMOUNT SUCH THAT THE RATIO OF SILICON BONDED SILOXANE FUNCTIONAL GROUPS GLYCERINE OH IN EXCESS OF DICARBOXYLIC ACID GROUPS IS FROM 0.1:1 T 0.29:1, AND THEREAFTER REACTING THE SILOXANE-GLYCERINE ESTER SO FORMED WITH AN ADDITIONAL AMOUNT OF AN ACIDIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF DICARBOXYLIC ACIDS AND ANHYDRIDES THEREOF IN AMOUNT OF THE THAT THE TATIO OF GLYCERINE OH TO SUM OF THE SILICON BONDED SILOXANE FUNCTIONAL GROUPS PLUS THE TOTAL DICARBOXYLIC ACID GROUPS IS FROM 0.9 TO 1.2.

Claim 2

A METHOD OF PREPARING THERMOSETTING RESINOUS MATERIALS WHICH COMPRISES REACTING A RESSILOXANE CONTAINING FROM 0.9 TO 2.1 SILICON-BONDED MONOVALENT HYDROCARBON RADICALS PER SILICON ATOM, SAID RADICALS BEING SELECTED FROM THE GROUP CONSISTING OF SATURATED ALIPHATIC RADICALS OF LESS THAN SEVEN CARBON ATOMS, AND MONOCYCLIC ARYL RADICALS AND FROM .05 TO 2 SILICON-BONDED SILOXANE FUNCTIONAL GROUPOS PER SILICON ATOM, SAID GROUPS BEING SELECTED FROM THE GROUP CONSISTING OF ALKOXY AND ACYLOXY RADICALS, SAID ACYLOXY RADICALS BEING OF THE FORMULA RCOO- WHERE R IS A HYDROCARBON RADICAL, THE REMAINDER OF THE VLENCES OF THE SILICON BEING SATIFIED WITH OXYGEN ATOMS, WITH A GLYCEROL ESTER FORMED BY REACTING GLYCERINE WITH AN ACIDIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF DICARBOXYLIC ACIDS AND ANHYDRIDES THEREOF IN AMOUNT SCUH THAT THE RATIO OF GLYCERINE OH TO DICARBOXYLIC ACID GROUPS IS FROM 2.25:1 TO 3:1, SAID POLYSILOXANE AND SAID GLYCEROL ESTER BEING REACTED IN AMOUNT SUCH THAT THE RATIO OF SILICON BONDED SILOXANE FUNCTIONAL GROUPS GLYCERINE OH IN EXCESS OF DICARBOXYLIC ACID GROUPS IS FROM 0.1:1 T 0.29:1, AND THEREAFTER REACTING THE SILOXANE-GLYCERINE ESTER SO FORMED WITH AN ADDITIONAL AMOUNT OF AN ACIDIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF DICARBOXYLIC ACIDS AND ANHYDRIDES THEREOF IN AMOUNT OF THE THAT THE TATIO OF GLYCERINE OH TO SUM OF THE SILICON BONDED SILOXANE FUNCTIONAL GROUPS PLUS THE TOTAL DICARBOXYLIC ACID GROUPS IS FROM 0.9 TO 1.2.
