Synthesis and Heterogeneous Structure of Anionic Networks of Oligoester Acrylates

Anionic polymerization has been used for the synthesis of polymeric networks based on α,ω-dimethacrylbis(triethylene glycol) phthalate, α,ω-dimethacrylbis(diethylene glycol) phthalate, and α,ω-dimethacrylbis(ethylene glycol) phthalate. The dependence of network polymer yields on catalyst concentration has a maximum. The correlation between the value and position of maxima and the length of the initial oligomeric chain has been established. The network polymers were studied by use of small-angle x-ray scattering. The parameters of heterogeneous structure and their relation to the peculiarities of the polymerization process have been established. It was established that the microheterogeneous structure of the networks is determined by the geometric characteristics of the initial oligomeric chains and the conditions of synthesis.
