Synthesis of Fungicidal Vinyl and Acrylic Latices by Emulsion Polymerization

摘要

Latex emulsions were prepared in which experimental fungicidal compounds were copolymerised into the resin matrix. The latices were laboratory tested for antifungal activity and subsequently formulated as internal/external paints. The paints were exposed under tropical conditions for evaluation of long-term growth-free performance. The monomers pentachlorophenyl acrylate (PPA) and pentachlorophenyl methacrylate (PPMA) were synthesised and incorporated into latices by emulsion polymerization at various levels in the general vicinity of 2% w/w and 3% w/w. Emulsion copolymers were prepared by combining various mixtures of vinyl acetate, methyl methacrylate, methacrylic acid, ethyl and butyl acrylates with the experimental monomers. By appropriate formulation, stable fine-particle emulsions were prepared exhibiting both antifungal activity and suitable film-forming properties. (Author)
