Abstract
CONCLUSIONS (1) Copolymerization constants, r 1 and r~ were determined in copolymerization of GMA with BMA, GMA with MA and BMA with MA. (2) It was found that GMA is the most reactive and MA the least active monomer in the systems investigated. (3) In the copolymcrization of GMA with BMA an azeotropic mixture, with a content of 30 moles-~ of BMA in the initial monomer mixture, is formed. (4) The activity factors, Q and e were determined for GMA and MA according to the Alfrey and Price system. (5) The composition of ternary copolymers of BMA, GMA and MA were estimated from the copolymerization constants obtained. Experimental and calculated data showed satisfactory agreement.
