摘要： Provided is an aqueous composition comprising dispersed particles that comprise a polymer, wherein the polymer comprises, by weight based on the weight of the polymer, a) 60% to 99.95% polymerized units of one or more (meth)acrylate ester, b) 0.05% to 6% polymerized units of one or more N-vinyl lactam, c) 0% to 39.95% polymerized units of one or more other monomers. Also provided is a method of making that composition, a process for producing an article using that composition, and a method of bonding two substrates using that article.

摘要： The present disclosure provides an adhesive composition. The adhesive composition contains (A) multi-stage latex polymer particles, (B) a linear diamine base, and (C) an ethoxylated surfactant. The (A) multi-stage latex polymer particles include (i) a first-stage polymer containing acrylic acid monomer and a first vinyl monomer, and (ii) a second-stage polymer containing a meth acrylic acid monomer and a second vinyl monomer, with the proviso that the second vinyl monomer is different than the meth acrylic acid monomer. The first-stage polymer is bound to the second-stage polymer.

摘要： The present disclosure provides an aqueous composition. The aqueous composition includes multi-stage latex polymer particles. The multi-stage latex polymer particles include (A) a first-stage polymer containing (i) an n-methylol functional monomer and (ii) a first vinyl monomer; and (B) a second-stage polymer containing (i) a formaldehyde-scavenging monomer and (ii) a second vinyl monomer. The first-stage polymer is bound to the second-stage polymer.
