Abstract The effects of injecting ethylene, propylene, 1-hexene, 2-methylpropene, 3,3-dimethyl-1-butene, cis-2-butene, trans-2-butene, 2,3-dimethyl-2-butene, cyclopentene, styrene, 1,3-butadiene and 1,4-pentadiene during polymerisations of ethylene and propylene were investigated. Catalysts used were a supported magnesium chloride/ethyl benzoate/titanium tetrachloride ballmilled catalyst and precipitated magnesium chloride /2-ethylhexanol/titanium tetrachloride/diisobutyl phthalate catalysts activated with triethylaluminium in the presence of ethyl benzoate. The instantaneous polymerisation rate was observed by continuous monitoring of the monomer consumption, the time resolution of the measurements being less than one second. 40 refs.
