Abstract
Abstract Novel derivatives of maleinized fatty acids are disclosed. The derivatives comprise mono-esters of both a selected type of diol and an alkylene oxide, they contain free carboxyl and hydroxyl groups and have acid values of 40-100 mg KOH per g. They are useful film-forming components of high-solids coating compositions.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
180 words
A derivative of an autoxidisable maleinised monocarboxylic fatty acid, said derivative being the product obtained by heating together: a. an autoxidisable maleinised monocarboxylic fatty acid comprising the reaction product of 1 mol of maleic anhydride per mol of monocarboxylic fatty acid and b. a diol selected from 2,2-bis (4-hydroxy cyclohexyl)propane and the reaction product of 1 mol of 2,2-bis (p-hydroxy phenyl)propane with 2 mol of an alkylene oxide selected from ethylene, propylene and butylene oxide, so as to form a mono-ester of said diol and open the maleic anhydride ring, and reacting the resulting ring-opened product by heating with c. an alkylene oxide selected from ethylene, propylene and butylene oxide and a compound of the formula: ##EQU4## where x, y and z are integers and x + y + z = 4-6 inclusive, so as to obtain a mono-ester of said oxide (c), said derivative being characterised by having both carboxyl and hydroxyl groups, and an acid value of 40-100 KOH/gm and being further characterised by the presence of a mono-ester linkage of (b) and a mono-ester linkage of (c).
Claim 2
Dependent Claim
180 words
A derivative of an autoxidisable maleinised monocarboxylic fatty acid, said derivative being the product obtained by heating together: a. an autoxidisable maleinised monocarboxylic fatty acid comprising the reaction product of 1 mol of maleic anhydride per mol of monocarboxylic fatty acid and b. a diol selected from 2,2-bis (4-hydroxy cyclohexyl)propane and the reaction product of 1 mol of 2,2-bis (p-hydroxy phenyl)propane with 2 mol of an alkylene oxide selected from ethylene, propylene and butylene oxide, so as to form a mono-ester of said diol and open the maleic anhydride ring, and reacting the resulting ring-opened product by heating with c. an alkylene oxide selected from ethylene, propylene and butylene oxide and a compound of the formula: ##EQU4## where x, y and z are integers and x + y + z = 4-6 inclusive, so as to obtain a mono-ester of said oxide (c), said derivative being characterised by having both carboxyl and hydroxyl groups, and an acid value of 40-100 KOH/gm and being further characterised by the presence of a mono-ester linkage of (b) and a mono-ester linkage of (c).
Claim 3
Dependent Claim
30 words
The derivative of claim 1 wherein (c) is a compound of the formula: ##EQU5## where x, y and z are integers and x + y + z = 4-6 inclusive.
