摘要：
A process for the polymerization of a polymer from an a-olefin monomer and one or more a-olefin comonomers in the presence of a catalyst, the process having a variation of reactor temperature and monomers concentrations (VTC) higher than 0, wherein the variation of reactor temperature and monomers concentrations (VTC) fulfils the criteria of equation (I): wherein Tf, Tb and Tt are the inlet feed temperature, the reactor temperature positioned 90° or more from the feeding point and the outlet temperature, respectively. (C8lC2)in and (C8lC2)out are the ratios of the concentrations of comonomer to monomer at the inlet and outlet, respectively.
