摘要：
TITANIUM TRICHLORIDE FOR USE AS CATALYST COMPONENT IN STEREOREGULAR OLEFIN POLYMERIZATION IS PREPARED BY GRADUAL ADDITION OF A SOLUTION OF TITANIUM TETRACHLORIDE IN INERT DILUENT TO A SOLUTION OF TRIALKYL ALUMINUM IN INERT DILUENT. THE MIXTURE IS PREPARED AND HELD AT A TEMPERATURE BELOW -30*C. AND MOST ADVANTAGEOUSLY BELOW -50*C. UNTIL ADDITION IS COMPLETE, IS THEREAFTER GRADUALLY WARMED UP TO NOT ABOVE 80*C. UNTIL CONVERSION TO TICL3 IS COMPLETE, AND IS THEN HEATED TO AN ELEVATED TEMPERATURE AT WHICH THE TICL3 IS CONVERTED TO THE VIOLET FORM.
