HYDRODYNAMIC AND CONFORMATIONAL CHARACTER ISTICS OF COPOLYMERS OF AMINOALKYL METHACRYLATES AND ALLYL GLYCIDYL ETHER

Water-soluble copolymers of dimethylaminoethyl methacrylate and allyl glycidyl ether were synthesized using radical copolymerization. Molecu lar masses of synthesized samples were determined via viscosimetric an d sedimentation measurements. The Mark-Kuhn-Houwink equation constants for the system studied were compared with those for the copolymer of diethylaminoethyl methacrylate and for homopolymers of aminoalkyl meth acrylates. The low polydispersity found (M(z) / M(w) = 1.5 - 1.8) is c haracteristic of copolymers of allyl monomers and can be explained by the high probability of these monomers entering the reactions of chain transfer. The values of the Kuhn segment for the copolymer of dimethy laminoethyl acrylate and allyl glycidyl ethers, A(av) = 36 x 10(-8) cm , is on the same order as for the copolymer of diethylaminoethyl metha crylate.
