Terpolymer alkylated phenol |
| abstract |
Phenols alkylated with high molecular weight ethylene-propylene-diene terpolymers are obtained in essentially quantitative yields and with no measurable fragmentation of terpolymer by reacting terpolymer with a large excess of phenol, in the presence of BF3 as catalyst, at alkylation temperatures of about 170 DEG -300 DEG F. The preferred terpolymers consist essentially of about 35-45 mole percent propylene, 65-55 mole percent ethylene, and about 1.0-2.5 mole percent of a 5-alkenyl-2-norbornene such as 5-ethylidene-2-norbornene. The novel terpolymer alkylated phenol compositions are useful as intermediates for the preparation of multifunctional addition agents for lubricating oils, for example addition agents having combined dispersant-viscosity index improving properties. |
