    摘要： High solids, low viscosity, alkaline-curable, thermosetting cationic vinyl ester based polymer latices, characterized by the high molecular weight of the polymer therein, are prepared by polymerizing at least 5% of selected vinyl esters (up to C.sub.6), 0.5-10% of a self-crosslinking cationic quaternary ammonium monomer, and optionally a vinyl polymerizable monomer such as butyl acrylate, ethylene, acrylamide, diallyl maleate, and/or 2-hydroxyethyl acrylate. The polymerization is carried out in the presence of water, a watersoluble cationic azo initiator, a water-soluble amino thiol salt chain transfer agent, and a cationic and/or nonionic surfactant. The latices are useful as formaldehyde-free binders for polyester nonwovens.

    摘要： Hot melt adhesive compositions are prepared from 20 to 98% by weight of a polylactide homo- or copolymer containing at least 20 molar percent of the lactide component; 2 to 80% by weight of a polar tackifier having a Ring and Ball softening point (as described by ASTM E-26) greater than about 60.degree. C.; 0 to 50% by weight of a plasticizer; 0 to 30% by weight of a wax diluent; 0-3% by weight of a stabilizer; and 0-20% of starch. By utilizing a naturally occurring, thermoplastic, biodegradable copolymer as the base polymer, these adhesives advance the state of the art of hot melt adhesives by alleviating the dependence on petroleum based materials and by allowing for the development of hot melt adhesives which either degrade naturally after coming in contact with the soil or which can be composted.

    摘要： Novel polymerizable imidazolidinone monomers, useful in the preparation of self-crosslinking polymers, have the general structure ##STR1## wherein R.sup.1 is H or a C.sub.1 -C.sub.6 linear or branched alkyl or hydroxyalkyl group; X is a divalent radical selected from the group consisting of --(CH.sub.2).sub.m --, ##STR2## with R being H or CH.sub.3, m being 0-5, and n being 1-5; R.sup.2 is H or CH.sub.3 ; R.sup.3 is H or ##STR3## with R' as defined above; and R.sup.4 and R.sup.5 are independently H or linear or branched C.sub.1 -C.sub.4 alkyl groups. In a preferred embodiment, aqueous emulsions of the imidazolidinone-containing polymers (e.g. 45-60% vinyl acetate, 34-52% butyl acrylate, and 3-6% imidazolidinone) and an acid-curing catalyst (e.g. ZnCl.sub.2) are used as formaldehyde-free binders for nonwoven textiles.
