摘要

正

The cationic polymerizations of 1

3-pentadiene were initiated by AlCl

in n-hexaneat 30℃ in the presence of alkyl halides

i.e.

tert-butyl chloride

tert-butyl bromide andisobutyl chloride. The effects of these halides on the polymer yield

molecular weight

crosslinking reaction

cyclization and polymer microstructure

have been investigated. Twomain side reactions

crosslinking and cyclization

were suppressed and reduced by theaddition of the halides. The proportion of 1

4 units of polymer chains was increasedby the presence of the halides

which reduced the polymer yield and the molecular weightof polymers.
