Abstract
An alkyd resin formed by reacting waste cooking oil, one or more aromatic polycarboxylic acids, aliphatic polycarboxylic acids, or esterified polymerization products, and one or more polyols.
Claims19
A method, consisting essentially of the steps of:
- providing waste cooking oil that is a reaction product of at least one vegetable oil, at least one animal fat, byproducts thereof, or combinations thereof, that has been heated and used in preparation of food, other products or combinations thereof, such that the waste cooking oil comprises at least one contaminant and at least about 4% by weight of free fatty acids;
- providing an aromatic or aliphatic polycarboxylic acid;
- providing a polyol;
- and
- reacting the above reactants to form an alkyd resin in a manner that reduces or prevents acrolein production.
