44317, 44330, 44331, 44347, 44351

Abstract:

Hydrocarbyl substituted C to C monounsaturated dicarboxylic acid, anhydrides or esters, e. g. polyisobutenyl succinic anhydride, preferably made by reacting polymer of C to C monoolefin, preferably polyisobutylene, having a molecular weight of about 1500 to 5,000, preferably with a C to C monounsaturated acid, anhydride or ester, preferably maleic anhydride, such that there are 1. 05 to 1. 25 dicarboxylic acid producing moieties per molecule of said olefin polymer used in the reaction mixture. The resulting materials are useful per se as oil additives, or may be further reacted with amines, alcohols, amino alcohols, boric acid, etc. to form dispersants.

Appl. No.:

10/191017

Inventors:

Rolfe J. Hartley - Cranbury NJ
Salvatore Rea - Franklin Square NY
Malcolm Waddoups - Westfield NJ

Assignee:

Infineum International Ltd.

International Classification:

C10M 1410

US Classification:

508291, 508364, 508365, 508408, 508433, 508438, 508579, 508584

Abstract:

The lubricating compositions of the present invention are designed for use in a four stroke outboard marine engine and contain an oil of lubricating viscosity, an ashless dispersant, a metal detergent, a rust inhibitor, a relatively high amount of ZDDP, and an amount of a molybdenum compound sufficient to provide the composition with 15-1,000 ppm by mass of molybdenum. An amount of about 15 ppm to 1,000 ppm by mass of molybdenum from a molybdenum compound has been found to be effective as an antiwear agent in combination with the high levels of ZDDP.

International Classification:

C10M 107/02
C10M 133/56

US Classification:

508287000, 508591000

Abstract:

A new low smoke two-cycle oil comprises highly reactive polyisobutylene (“HR-PIB”), a solvent additive package, and exhibits Kinematic viscosity of at least 6.5 mm/s at 100 C. and JASO M342 Smoke Index of at least 85. The new two-cycle oil is manufactured from an alternative starting material, which offers an efficient alternative as compared to polyisobutylene (“PIB”), which has traditionally been included in conventional two-cycle oils.
