摘要：
The kinetics of a three-dimensional (3D) polymerization reaction in alpha,omega-bis-(methacryloyl-hydroxyethylene-hydroxycarbonyloxy)-1,3-propylene was studied by pulsed NMR techniques. The results allow a microheterogeneous model of the 3D radical-initiated oligo(ether acrylate) polymerization to be refined, The reaction system is characterized by three components of the spin-spin relaxation time, corresponding to the bulk monomer anti polymer regions and a subsurface layer of the polymer grains formed. The subsurface layer exhibits a broad spectrum of the frequencies of molecular mobility.
