Multipolymers with Fischer-Tropsch olefins

Multipolymers consisting of ethylene, 1‐heptene, 3‐methylpentene and 4‐methylpentene were prepared with a heterogeneous Ziegler‐Natta catalyst. The polymers were prepared in such a way that the molar fraction of the comonomers remained the same. Copolymers of ethylene/1‐heptene and ethylene/4‐methylpentene were prepared in order to study the changes in polymer characteristics as one moves from an ethylene/linear alpha olefin copolymer through ethylene multipolymers to an ethylene/4‐methylpentene copolymer. The mechanical, rheological and application properties showed expected trends.
