The Suspension Copolymerisation of Butyl Methacrylate with Methacrylic Acid in the Presence of a Copolymer of 2-Acrylamido-2-Methylpropane Sulphonic Acid of Different Composition
An investigation was made of the influence of the composition of a copolymer of 2-acrylamido-2-methylpropane sulphonic acid with methyl methacrylate (MMA) on the suspension copolymerisation of butyl methacrylate (BMA) with methacrylic acid (MAA) and the particle size distribution of the polymer formed. With increase in the content of methyl methacrylate units in the studied polymeric dispersing agent, an increase was observed in the degree of dispersion of the BMA–MAA suspension copolymer, accompanied with an increase in the content of highly dispersed fraction. Possible reasons for the observed results are discussed.
