Notes:
Copolymers of pentachlorophenyl acrylate (M1) with both vinyl acetate and ethyl acrylate were prepared (in benzene at 60°C initiated by t-butyl peroxypivalate) at a variety of M1/M2 ratios. The reactivity ratios for the vinyl acetate (M2) copolymerizations were r1 = 1.44 and r2 = 0.039, while for ethyl acrylate copolymerizations r1 = 0.21 and r2 = 0.88. The glass transition temperatures were obtained as a function of the M1/M2 ratio. The values of Tg for the copolymers fell between those of poly(pentachlorophenyl acrylate) and either poly(vinyl acetate) or poly(ethyl acrylate). A series of bulk copolymers with low pentachlorophenyl acrylate content were studied as biocidal coatings using accelerated growth agar dish tests inoculated with Aspergillus sp., Pseudomonas sp., Alternaria sp., and Aureobasidium pullulans. The copolymers retarded or prevented growth but did not give a zone of inhibition around the coatings. Pentachlorophenol, when added to coating polymers, did exhibit a zone of inhibition due to migration of this biocide into the agar medium.
