摘要： This invention is directed to aqueous-based ethylene-vinyl acetate (EVA) polymer emulsions suited for use in heat seal applications. The EVA polymers of this invention are produced by a relatively low-pressure process, i.e., less than 2000 psig, preferably from about 1000 to about 2000 psig. The aqueous-based EVA based polymer emulsions contain crystalline segments resulting from ethylene linkages and are prepared by emulsion polymerizing ethylene and vinyl acetate, preferably with a carboxylic monomer, in the presence of a stabilizing system containing surfactant or a cellulosic protective colloid in combination with surfactant.

摘要： A method of improving the wet tensile strength of a cellulose-containing web includes applying to the web an aqueous binder emulsion and subsequently drying and curing the binder emulsion. The aqueous binder emulsion is prepared by emulsion-polymerizing a monomer mixture comprising vinyl acetate, ethylene, and an olefinically unsaturated crosslinking monomer in the presence of a phosphate ester surfactant wherein the at least one crosslinking monomer comprises a (meth)acrylamide moiety and a cellulose-reactive moiety. The binder emulsion may be applied to a cellulose-containing web to increase wet strength, aid in creping, or both.

摘要： This invention is directed to an improved nonwoven product comprising a nonwoven web of fibers bonded together with a sufficient amount of binder comprised of a polymer comprised of vinyl acetate, ethylene, and a crosslinking monomer to form a self-sustaining web. The improvement in the nonwoven product resides in the use of a polymer having a crystalline melting point (Tm) ranging from 35 to 90° C., preferably 50 to 80° C.; measured at a heat rate of 20° C./minute. The polymer should have a crystalline heat of fusion (Hf), which typically range from about 2 to about 50 joules per gram and a low glass transition temperature (Tg), e.g., from 10 to −40° C., typically −15 to −35° C.

摘要： This invention is an emulsion composition comprised of acrylic ester monomers polymerized in the presence of fully hydrolyzed poly(vinyl alcohol) or a partially hydrolyzed poly(vinyl alcohol) provided the molecular weight of the low molecular weight poly(vinyl alcohol) is from 5,000 to 13,000 as the only stabilizer and a chain transfer agent. The improvement over the known prior art is the ability to incorporate fully hydrolyzed poly(vinyl alcohol) without the need for other surfactants or special processing.
