Influence of poly(heteroarylenes) with different molecular masses on free-radical polymerization of methyl methacrylate

Polymer systems were prepared through the free-radical Polymerization of methyl methacrylate in the presence of 4 wt% dissolved poly(arylates). The latter polymers were shown to affect the parameters of the gel effect. It was demonstrated that, as the molecular mass of poly(imide) dissolved in methyl acrylate grows, the conversion corresponding to the onset of autoacceleration and the rate of polymerization at all stages of the process decrease. The data on the free-radical polymerization of methyl methacrylate carried out in the presence of model compounds (diimide and diester) provide evidence that the reactions of chain transfer to the benzene nuclei of poly(heteroarylenes) are not the only path of copolymer formation.
