DSC STUDIES ON BUTADIENE-OLEFIN COPOLYMER S, TERPOLYMERS AND THEIR HYDRATION PRODUCTS

Poly(butadiene-alt-1-olefin) copolymers and butadiene-alt-ethene)-co-( butadiene-alt-1-olefin)] terpolymers, and the hydrogenated products to o, has been characterized with the aid of differential scanning calori metry (DSC). Both the glass transition and the melting behaviour of th e partial crystallized products has been investigated. From the peak a rea the degree of crystallinity has been calculated in a first approxi mation. The results allow to draw conclusions about the crystallizatio n behaviour in relation to the number and length of the side chains an d about the course of the synthesis in question.
