摘要

An important method of the modification of the properties of poly(ethylene) and poly(propylene) is the copolymerization with α-olefins. The α-olefin behaves as a short branch in the structure, and the rheological and thermal properties of copolymers change significantly. A new method is suggested to evaluate the rheological and thermal properties of copolymers on the basis of homopolymer properties, by introducing a short branch degree parameter. The zero shear viscosity, characteristic relaxation time plateau modulus, fractional free volume, glass transition temperature and thermodynamical melting point were calculated.
