摘要： Vinyl acetate/ethylene (VAE) copolymer emulsions having extended shelf life which are particularly suited for use as binders of nonwoven substrates. The copolymer emulsions are prepared by incorporating 1 to 45 wt % tetramethylol glycoluril, based on the amount of vinyl acetate in the copolymer, into an aqueous dispersion of a copolymer consisting essentially of 60 to 94 wt % vinyl acetate, 5 to 30 wt % ethylene and 1 to 10 wt % of a crosslinkable comonomer. Suitable crosslinking monomers include N-acrylamidoglycolic acid and N-methylol acrylamide. Nonwoven products formed by depositing the emulsion onto a nonwoven substrate exhibit significantly improved resistance to organic solvents.

摘要： A two stage polymerization process for preparing a vinyl acetate/ethylene emulsion copolymer containing a monomer which is normally incompatible with vinyl acetate. In the first stage the vinyl acetate and ethylene and, optionally, an active crosslinking comonomer and/or latent crosslinking comonomer are free radical polymerized in the presence of a stabilizing system to yield a first stage polymer emulsion. When the free vinyl acetate monomer content of the first stage emulsion is less than about 5%, the second stage polymerization begins by adding the incompatible monomer. Preferably, there is no cessation of the addition of the free radical source during the transition from the first stage to the second stage polymerization. No additional stabilizing system is added to the reaction in the second stage.Vinyl acetate/ethylene/incompatible comonomer/latent crosslinking comonomer copolymers prepared by the two stage polymerization process are suitably used as binders for making nonwoven products.

摘要： This invention relates to a vinyl acetate-ethylene copolymer containing emulsion particularly adapted for the preparation of nonwoven goods. The vinyl acetate-ethylene emulsion is prepared by an improved process for producing an aqueous emulsion suitably adapted for producing non-woven goods said emulsion containing a vinyl acetate-ethylene copolymer wherein said copolymer contains from about 75-96% by weight of vinyl acetate. It is produced by forming an aqueous suspension of vinyl acetate, ethylene, and stabilizer, initiating the polymerization of the reaction mixture by the addition of catalysts, and adding from about 0.5-10% by weight of the vinyl acetate of a crosslinkable monomer. The improvement for enhancing the absorptivity of the copolymer comprises:pressurizing the reactor with ethylene to an initial ethylene equilibrium pressure of from about 100 to 1,000 psig;initiating the reaction mixture by the addition of catalyst at a temperature from about 10.degree.-35.degree. C. and bringing the reaction mixture to a reaction temperature of from 45.degree.-85.degree. C. and operating pressure within a period of not more than 2 hours and the reaction temperature exceeds the initiation temperature by at least 20.degree. C.;adding the crosslinkable monomer at a substantially uniform rate such that the major portion of monomer has been added by the time the vinyl acetate content in the emulsion has been reduced to a level of from 3-25% by weight of the emulsion;andcontinuing polymerization of the reaction mixture until the vinyl acetate content in said emulsion is reduced below about 1% by weight.
