โœฆ Synopsis


Heterogeneous radical polymerization of methacrylic acid (MAA) in benzene in the presence of poly(ethylene glycol) (PEG) and poly(N-vinylpyrrolidone) (PVP) was studied. The products of the polymerization are the interpolymer complexes of poly(methacrylic acid) (PMAA) with PEG and PVP. In spite of the daughter polymer PMAA being insoluble in the reaction medium, the polymerization proceeds via a template mechanism which is generally similar to the template polymerization of MAA in the presence of the same templates under homogeneous conditions. In a heterogeneous polymerization, competition between the two templates is possible: the PMAA macroradical with high selectivity chooses the much stronger template PVP.

Polymerization of acrylamide was studied in the presence of poly(ethylene glycol)s 200 and 400 (PEG) in two diluents, viz. water and methanol, using ammonium persulphate as radical initiator. The polymers prepared in methanol, in general, were of lower intrinsic viscosity than those obtained from an
