Calculation of the [#eta#] (M) relationship for ethylene/propylene copolymers from the relations for homopolymers

摘要

Intrinsic viscosity [#eta#]-weight-average molecular weight (M_w) relations were calculated for ethylene/propylene copolymers at varying copolymer compositions by using the principle of the two-parameter theory of dilute polymer solutions and by taking the conformational and interaction parameters for PE and PP.
