Abstract
PURPOSE: To obtain the titled copolymer for soft materials having improved resistance to heat distortion, transparency and heatsealing properties at a low temperature, by copolymerizing propylene with a specific α-olefin in the presence of a stereoregular polymerization catalyst, and terminating the reaction with carbon monoxide, etc.
CONSTITUTION: Propylene is copolymerized with a 1W12C α-olefin, e.g. hexene-1, in the presence of a stereoregular polymerization catalyst, e.g. a combination of a titanium component with an organoaluminum compound, and carbon monoxide or dioxide is then introduced into the polymerization system to terminate the copolymerization reaction substantially and give the aimed copolymer.
EFFECT: Carbon monoxide, etc. added to the system may terminate the reaction and prevent the deterioration of physical properties of the copolymer due to the molar concentration ratio between the propylene and the hexene-1 in the reaction system in the continued polymerization stage and a sharp increase in the hexene-1 content in the product copolymer.
