Abstract
PURPOSE: To obtain a copolymer having a wide MW distribution and excellent processability, by copolymerizing styrene with an α-olefin and/or a di(poly)ene in the presence of a premixed and aged mixture containing a specified catalyst, a specified polymerization activator, etc.
CONSTITUTION: In the production of a copolymer containing ethylene and an α- olefin of the formula: CH2=CHR, wherein R is a 1W6C alkyl, e.g., propylene, or of a multicomponent polymer containing in addition thereto, a linear or cyclic di(poly)ene monomer containing nonconjugated double bonds; an organic Al compound, e.g., triethylaluminum, a polymerization activator, e.g., ethyl trichloroacetate, and a V compound, e.g., VCl4, are premixed and aged, an the resulting aged mixture is introduced to a polyermization tank. The olefin copolymer of the purpose is obtained by further adding an organic Al compound and a polymerization initiator to the tank and polymerizing therein.
