The concentration effect on rheological properties of polychloroprene/piperylene-styrene copolymer blends has been investigated under steady shear Couette flow conditions. Rheological measurements, performed at various temperatures and a variety of copolymer content, show that effect of shear rate is more significant at the high concentrated adhesive systems and at 25-30wt% copolymer content. Such content of copolymer results in an appreciable decrease in adhesive viscosity and affords opportunity to restrict the use of volatile organic solvents in the composition. Concentration-temperature analogies were applied. The superposed data were measured at different temperature and various copolymer contents and shifted to the unmodified adhesive data. The influence of the copolymer and temperature on shift factor decreases when adhesive solid content increases.
