摘要： Process for producing a propylene/1-pentene polymer in the presence of a Ziegler-Natta catalyst system with the monomer reactants being in the vapor phase while the reaction is in process and with no liquid component being present in the reaction zone while the reaction is in progress. Different ways of introducing the reactants are disclosed (partly in liquid phase then immediately evaporated or not, preheated or not, mixed with the comonomer or not).

摘要： A Ziegler-Natta type catalyst having an improved hydrogen response provides for narrowing of the MWD of resulting polyolefins polymerized using such catalyst, with such catalyst generally made by a) 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; b) contacting reaction product A with a first halogenating/titanating agent to form reaction product B; and c) contacting reaction product B with a second halogenating/titanating agent to form a catalyst component; wherein in at least one of steps b) and c), the halogenating/titanating agent is a blend of Ti(OPr)4 and TiCl4. Catalyst components, catalysts, catalyst systems, polyolefin polymers, and methods of forming each are disclosed.
