Frequency Distribution of Fragments

An original chemical method elaborated for the quantitative study of the monomer unit distribution (137,142) consists of copolymer pyrolysis with subsequent gas-chromatograph analysis of the decomposition products. Good correlation was found between the experimentally measured frequency distribution of fragments of copolymers with up to 50 mol-% of propylene and those calculated from r, t2 values [system VOCI3—Al2(C2H5)3Cl3, =0.87] (142).
