“…Thermal decomposition of polymer blends has received a fair amount of attention in the past few years and a number of experimental studies have been published. [1][2][3][4][5][6] The chief aim of these works was to investigate the influence of the presence of one homopolymer on the decomposition rate of the other component of the polymer blend. Using the thermogravimetric method, two main stages of weight loss connected with the destruction of both homopolymers in their blends were usually observed.…”

SYNOPSISStudies of thermal degradation in nitrogen atmosphere of honiopolymers: polypropylene (PP), polyethylcne (PE), poly(viny1idene chloride) (PCVD), and polyacrylonitryle (PAN) as well as of their blends were carried out using the tlierriiogravimetric method. The investigations performed at different heating rates led to thermogravinietric curves which made it possible for the kinetic parameters characterizing thermal degradation, i.e. ~ activation energy E and reaction order n, of the homopolymers and polymer blends in dependence on blend composition to be determined. PP and PE blends show higher thermal stability as compared with pure PP in contrast t o the results obtained for PCVD with PAN blends.
