Procedure

A 2 L Parr reactor was heated to 70° C. and charged with 270 g of propylene and pressured with 0.14 L of hydrogen. 7-Octenylsilane (containing about 14.6 percent of 6-octenylsilane) 0.13 wt percent based on total monomer content, dissolved in 0.5 ml of toluene and pressured to 100 psig over the reactor pressure with N2 was charged to the vessel. To the vessel was then added 12 μmoles of the Zr-containing catalyst, slurried in hexane under N2 pressure of 100 psig above the reactor pressure to initiate the polymerization. The polymerization was continued for 30 minutes and resulted in the formation of 45.3 g of octenylsilane modified polypropylene. The polymer had a mwt of 459,000 and a MWD of 3.2. The copolymer contained added LCB as shown by the increase in solution viscosity as a function of increased absolute molecular weight and an increase in the strain-hardening in extensional flow as a function of extension rate when compared to a polypropylene made under comparative conditions. Based on such analysis the octenylsilane-containing polymer has from 0.2 to 0.5 tetrafunctional branch sites/chain.
