Abstract
An emulsion polymerization copolymer comprising 59-77 phr butadiene, 10-16 phr styrene; 10-16 phr acrylonitrile; and from 3-9 phr methacrylic acid is soluble in acetone for U.S. EPA-exempt, low-VOC emissions, while also soluble in toluene. The composition is formulated with a tackifying resin; a plasticizer oil; and a U.S. EPA-exempt solvent, preferably acetone, to make an adhesive.
