BLOCK-COPOLYMERS IN ELASTOMERIC ROOF COATINGS
Disclosed herein are elastomeric roof coatings containing a block-copolymer, for example for use as a dispersant. In some embodiments, the roof coating compositions can comprise an all-acrylic or styrene-acrylic latex comprising a block-copolymer used in the latex polymerization. The block-copolymers have a molecular weight exceeding 5000 g/mol wherein the block copolymer has a first block comprising of alkyl acrylate and a second block comprising units of an ethylenically unsaturated monomer with sulfonic acid groups.The modified elastomeric roof coating compositions are advantageous for reasons of water resistance, wet adhesion, tensile strength, and elongation. Methods of making and using the elastomeric roof coating compositions are also disclosed.
