Abstract:
1. A process for preparing an olefin polymerization catalyst comprising sequentially mixing: (i) a solution of a mixture of a compound of the formula (R (ii) a solution of HCl or an organic chloride of the formula R (iii) rapidly adding a solution of a titanium compound of the formula (R a) heating one of the mixture of component (ii) and the solution of the titanium compound or both to a temperature sufficient so that upon mixing said temperature is obtained within 20 seconds; or b) heating one of the mixture of step (ii) and the solution of titanium compound or both to a temperature insufficient so that upon mixing said temperature is not obtained and heating the resulting mixture at a rate to obtain said temperature within 20 seconds; and combining the resulting hot mixture with (iv) a compound of the formula (R
