Abstract
The molecular weight characteristics of the polymer obtained by suspension polymerization of methyl methacrylate in the presence of polymeric surfactants - (co)polymers of 2-acrylamido-2-methylpropane sulfonic acid, sodium salt of methyl methacrylate copolymer with methacrylic acid and acrylamide copolymer with acrylonitrile and acrylic acid are studied. It was found that the highly dispersed fraction (0.5–2 μm) of polymethyl methacrylate has an increased molecular weight and even at a content less than 1% has a noticeable eff ect on the average molecular weight. It is shown that an eff ective way to reduce the content of polymer particles 0.5–2 μm is the use of a dispersant, in which the colloidal solubility of methyl methacrylate is minimal.
