Abstract
An ethylenically unsaturated vegetable oil is modified by the addition of an enophile or dienophile having an acid, ester or anhydride functionality. The modified vegetable oil is then reacted with a polyethylene glycol (PEG) derivative along with a functional vinyl monomer or a polyethylene glycol derivative that contains a vinyl functionality to form a vegetable oil derivative. The vegetable oil derivative is useful in forming latexes and coatings.
Claims5
A latex of a polymer comprising the polymerization product of:
- an ethylenically unsaturated monomer;
- and
- the reaction product of (a) an unsaturated vegetable oil that has been modified by the addition of an enophile or dienophile having an acid, ester or anhydride functionality and (b) either a polyethylene glycol (PEG) derivative along with a functional vinyl monomer, or a polyethylene glycol (PEG) derivative that contains a vinyl functional group, wherein the reaction product comprises an ester functionality formed between the polyethylene glycol (PEG) derivative and the enophile or dienophile.
