TERNARY OLIGOMER SYSTEM WITH ACTIVE SOLVENT AND STRUCTURE OF COATINGSPREPARED FROM CROSS-LINKED EPOXY POLYMERS

Concentration dependences of the relative viscosity and intensity of R ayleigh light scattering in chloroform solutions of ED-20 epoxy resin, PPG-ZAK oligomer epoxydated rubber, and their model formulations and in monoepoxy compounds (E-10 Cardura) were studied. The limiting conce ntrations of oligomers in the ternary system calculated in the cluster lattice model approximation are compared with data on elastic light s cattering in solution of oligomers in chloroform and E-10 Cardura, and with a prescribed composition of organic phase of the filled formulat ion. The structure of cross-linked epoxy polymers in the coatings on t he model substrates was studied by IR multiple attenuated total intern al reflection spectroscopy.
