Abstract
The present invention is an acrylate oligomer represented by the formula (I) where R1 is hydrogen or methyl; R2 is an alkyl group having from 2 to 18 carbons, inclusive; R3 is hydrogen or hydroxyl; Y is hydrogen or an initiator residue; Z is a single bond or methylene; and n is an integer from 9 to 40, inclusive. The present invention also includes acrylate oligomer emulsions including the disclosed oligomer and fluorine-free treating compositions including the acrylate oligomer emulsion. Methods of making and using such compositions are also disclosed.
