Hydrogen response Ziegler-Natta catalyst for narrowing MWD of polyolefin, method of making, method of using, and polyolefins made therewith

A catalyst produced by a process comprising:

• a) contacting a catalyst component with an organoaluminum preactivating agent, wherein the catalyst component is produced by a process comprising,
• i) contacting a soluble magnesium dialkoxide compound of the general formula Mg(OR″)2 with a halogenating agent capable of exchanging one halogen for one alkoxide to form a reaction product A, where R″ is a hydrocarbyl or substituted hydrocarbyl having from 1 to 20 carbon atoms;
• ii) contacting reaction product A with a first halogenating/titanating agent to form reaction product B;
• and
• iii) contacting reaction product B with a second halogenating/titanating agent to form a catalyst component;
• wherein the first halogenating/titanating agent is a blend of Ti(OPr)4/TiCl4.
