Abstract
Strong heat-sealable nonwoven fabrics, textiles, papers and other substrates which have been treated with a polymer latex derived predominantly from polymers of vinyl halides or vinylidene halides which have been overpolymerized with one or more of .alpha.,.beta. -olefinically unsaturated carboxylic acids, olefinically unsaturated amides or their N-alkylol and N-alkoxyalkyl derivatives, and esters of acrylic and methacrylic acids. Copolymers of vinyl halide or vinylidene halide with vinylidene monomers containing a terminal CH.sub.2 =C< group may also be overpolymerized in the same way in making the heat sealable articles.
