Abstract
Heat resistance binders for flexible polyester webs may be prepared using an emulsion polymer,the polymer being prepared by a two-stage polymerization procedure wherein a first stage is prepared based on a relatively low Tg ethylene vinyl acetate polymer and a second stage higher Tg polymer thereby combining the advantageous flexibility and film forming properties of the ethylene vinyl acetate copolymer with the stiffness and heat resistance of the higher Tg copolymer.
