An aqueous composition suitable for use as an improved elastomeric coating, coke, sealant, fabric treatment or pressure sensitive adhesive upon drying has a glass transition temperature (Tg) of -90 to 20 ° C and at least one ethylenically unsaturated nonionic acrylic. 0-7.5% by weight of the ethylenically unsaturated acid monomer based on the total weight of the monomers and the polymer is converted to 90-99.7% by weight of the monomer, based on the total weight of the polymer, and subsequently the total of the polymer 0.01-0.099% by weight t-alkyl hydroperoxide, t-alkyl peroxide or t-alkyl perester having a t-alkyl group containing at least five carbon atoms by weight and optionally the remaining monomers in the presence of at least one other oxidant At least half of which is provided to comprise the predominant acrylic aqueous emulsion polymer formed by the free radical polymer being converted to the polymer. Methods of preparing emulsion polymers, methods of coating substrates to provide elastomeric coatings to substrates, methods of applying aqueous coke or sealant compositions to substrates, methods of providing treated fabrics, and methods of providing pressure sensitive adhesives to substrates are also provided. |
