摘要：
A copolymerization model of ethylene and a alpha-olefin describing the monomer uptake and the quality of the polymer produced, namely M(n), M(w), M(z), the distribution of molecular weight, short branching index and double bonds, is presented. This model assumes the existence of several types of active sites (2 or 3) and do not involve any limiting diffusion. It is applied to ethylene and butene-1 bulk copolymerization at high pressure and high temperature. Parameters are identified with CSTR experiments.
