Abstract
Crystalline block copolymers of normal alpha-olefins and branched chain olefins of the formula CH2=CHR in which R is a C3-C10 branched chain alkyl group are made by polymerizing a normal alpha-olefin in the absence of a molecular weight control agent to form a first living polymer and polymerizing the branched chain olefin in the presence of the first living polymer, a molecular weight control agent being admitted to the polymerization zone some time after the start of the polymerization of the branched chain olefin, both stages of polymerization being effected in the presence of a catalyst obtained from (a) a solid crystalline compound of a metal from Groups IV, V, VI, VII and VIII of the Periodic Table, the metal being in a valency state lower than its maximum, and (b) an organometallic compound or hydride of a metal of Groups I, II or III, or an organometallic compound of tin. Normal and branched chain olefins specified are ethylene, propylene, pentene-1, heptene-1, 3-methylbutene-1, 3-methylpentene - 1, 4 - methylpentene - 1, 3-ethylpentene-1 and 4,6-dimethylheptene-1. The preferred molecular weight control agent is hydrogen. The resulting copolymers are insoluble in hot acetone and are capable of forming transparent mouldings. The example describes polymerizing decene-1 in heptane in the presence of a titanium trichloride/aluminium diethylchloride catalyst, continuing polymerization with 4-methylpentene-1, and admitting hydrogen to the polymerization after the start of the polymerization of the 4-methylpente-1.
