Abstract
The IR MATIR spectra in the 1535-1680 cm(-1) range were studied for epoxy-D PP resins (M-N = 1650-3400) in coatings on germanium substrate obtained fro m oligomer solutions in methylene chloride and Cellosolve with the concentr ation c = 10-50%. The concentration dependences of the relative viscosity o f narrow-MWD fractions of epoxy oligomers(M-N = 1500-5300) in chloroform an d Cellosolve solutions were studied. The structure of the network of cross- linked polymers based on epoxy (M-N = 2100-3400) and phenol- formaldehyde ( M-N = 860) resin was studied by the electron- microscopic silver chloride d ecoration method. Based on the cluster lattice model, the optimal molecular weight and the concentration regimes were determined for epoxy oligomers i n the lacquer composition for can protection.
