Abstract

Latices from polyvinyl acetate or copolymers vinyl acetate (VAC) — acrylamide (AA) and methyl methacrylate (MMC)- butyl methacrylate (BA) were prepared by radical polymerisation. The influence of the amount of the surfactants or the chemical structure and the quantity of monomers on the particle size of the latex was investigated. The increasing of the quantity of the comonomers leads to the decreasing of particle size in the case of latex based on MMC-BA and VAC-AA. The influence of the amount of surfactant was investigated in the homopolymerisation of VAC. The use of latex on the base of MMC-BA in ink for polypropylene and of homopolymer VAC in adhesives for wood were investigated. The cross-linking of the latex was effected by the epoxy resin and the resultant adhesives for wood were of class D3 stability in accordance with EN204.
