Aqueous adhesive compositions

A roofing material comprising:

• a polymeric roofing membrane;
• and
• an adhesive on a surface of the polymeric roofing membrane, wherein the adhesive comprises:
• an aqueous carrier liquid;
• a latex copolymer formed from reactants comprising a chain transfer agent and a vinyl monomer having an alkyl group including between 2 and 20 carbon atoms, wherein the reactants comprise at least 20 wt. % of the vinyl monomer having an alkyl group including between 2 and 20 carbon atoms, based on the total weight of ethylenically unsaturated monomers used to make the latex copolymer, and wherein a homopolymer formed from the vinyl monomer exhibits a glass transition temperature of between about −10° C. and about 30° C., and wherein the latex copolymer exhibits a glass transition temperature of less than about −15° C.;
• and
• wherein the latex copolymer exhibits a gel fraction of between 0% and about 5% and a solubilized portion of the latex copolymer exhibits a weight average molecular weight of less than about 230,000 g/mol,
• wherein a coating formed from the aqueous adhesive composition exhibits a dry adhesion of greater than about 4 pounds per linear inch when applied between a thermoplastic polyolefin roofing membrane and a plywood roofing substrate at an average coat weight of about 6 lbs/100 ft2 and subjected to 180° peel testing according to ASTM D903 with a 2-inch per minute pull rate;
• and
• a backing membrane removably on the adhesive.
