摘要:
This invention provides stable waterborne polymer compositions, which are stabilized against gelling, comprising a stable waterborne polymer composition having a Tg of greater than about 0° C. and comprising an acetoacetoxy-type functional polymer, a poly(alkylenimine), and a nonionic surfactant having a hydrophilic-lipophilic balance (HLB) of at least about 17.5. The waterborne polymer compositions of the invention are particularly useful in a variety of adhesive formulations such as pressure sensitive adhesives, laminating adhesives, and the like. Methods of making stable waterborne polymer compositions are also disclosed.
摘要:
This invention provides low foam waterborne polymer compositions stabilized against gelling due to the addition of a poly(alkylenimine) by addition of surfactants. Preferably, the surfactants are nonionic surfactants having a hydrophilic-lipophilic balance (HLB) of at least about 17.5. Polymerization in the presence of phosphate surfactants has been found to yield low foam polymers. These stable low foam polymer compositions are useful in a variety of coating formulations such as, for example, paints, inks, sealants, textile backcoatings, adhesives and the like. Methods of making stable low foam polymer are also disclosed.

摘要:
The present invention is directed to polymer compositions containing a vinyl polymer component (A), formed by polymerization of .alpha.,.beta.-ethylenically unsaturated monomers, one which contains at least one hydroxyl group and one which contains no hydroxyl groups; a crosslinker component (B); an additive component (C); and a solvent component (D). The composition is useful for backcoating woven substrates and as a binder composition for non-woven substrates.

摘要:
Aqueous dispersions of water-insoluble polyolefin-based adhesion promoters are formed by dissolving the adhesion promoter in at least one olefinically unsaturated monomer, forming a mini-emulsion with high shear in the presence of water, surfactant and other additives, and then polymerizing the monomer with a monomer-soluble, substantially water insoluble radical initiator. The polymerized product, a stable dispersion (latex) of polyolefin adhesion promoter and polymerized monomer in water, is useful as a primer or as an additive for improving the adhesion of coatings to polyolefin substrates.
