Woodworking adhesives based on multistage emulsion polymer |
| abstract |
A woodworking adhesive composition prepared by a two stage emulsion polymerization procedure wherein the first stage comprises the step of emulsion polymerizing vinyl acetate with 0.1 to 6% by weight of a post-crosslinking monomer in the presence of polyvinyl alcohol to produce a polyvinyl alcohol stabilized copolymer having a Tg within the range of +10 DEG to +40 DEG C. and containing no pre-crosslinking monomers and the second stage comprises the step of emulsion polymerizing methyl methacrylate to produce a methyl methacrylate homo- or copolymer containing at least 75% by weight methyl methacrylate and having a Tg within the range of +50 DEG to +120 DEG C., further characterized in that the ratio of the polymer produced in the first stage to the polymer produced in the second stage is within the range of 10:1 to 10:6 and wherein the first stage polymer and second stage monomer mixture are not equilibrated prior to the second stage polymerization. |
