SCALABLE PRODUCTION OF PRECISION HYDROCARBONS FROM TRIALKYLALUMINUM VIA TERNARY LIVING COORDINATIVE CHAIN TRANSFER POLYMERIZATION |
摘要 |
Disclosed is a method of producing a polyolefin composition comprising contacting a metallocene pre-catalyst, a co-catalyst, a primary surrogate, and a secondary surrogate; adding a first olefin monomer; and polymerizing the first monomer for a time sufficient to form the polyolefin. Also disclosed is a method of producing a block polyolefin composition comprising contacting a metallocene pre-catalyst, a co-catalyst, a primary surrogate, and a secondary surrogate; polymerizing the first monomer for a time sufficient to form the polyolefin; adding a second monomer; and polymerizing the second olefin monomer for a time sufficient to foam said block polyolefin composition. The method allows for the production of polyolefins of low molecular weights and narrow molecular weight distributions. |
