摘要
Viscometric behaviors of dilute solutions of random ethylene-vinyl acetate (EVA) copolymer in the temperature range of 5-65°C in four solvents;1,2-dichloroethane, cyclohexane, xylene and chloroform are studied. It is found that association of EVA molecules occurred by two patterns of intrachain and interchain interactions. The degrees of association are dependent on solvent properties, EVA concentrations and annealing temperature of preparation of EVA solution.
