Product 1

HCID 86748443Styrene octene

Procedure

A styrene-octene copolymer was prepared in an inert environment under standard temperature and pressure by mixing 47.1 grams of styrene with 453.0 grams of octene in a beaker. After stirring, 4.0 milliliters of a 25% DIBAC solution was added to the beaker. The mixture was held for 30 minutes without stirring. A 3.0 milliliter portion of the catalyst mixture prepared in Example 1 was added to the beaker while stirring continuously. The entire mixture was allowed to react. The subsequent copolymer was subsequently tested and found to have a 95.3% conversion to polymer with an inherent viscosity of 28.1 deciliters/gram.
