Appl. No.:
5/696151
Inventors:
Roy I. Yamamoto - Wappingers Falls NY
Abraham Morduchowitz - Monsey NY
Wheeler C. Crawford - Houston TX
Carmen M. Cusano - Poughkeepsie NY
Assignee:
Texaco Inc. - New York NY
International Classification:
C10M 132
US Classification:
252 515A
Abstract:
A complex product of 1). an interpolymer of an N,N-dialkylaminoalkyl methacrylamide, C. sub. 1 -C. sub. 6 alkyl methacrylate, C. sub. 10 -C. sub. 14 alkyl methacrylate and C. sub. 16 -C. sub. 20 alkyl methacrylate monomers and 2). a liquid poly(alkene-1) of a molecular weight between about 200 and 10,000 prepared by polymerizing the monomers comprising said interpolymer in the presence of said liquid poly(alkene-1). A mineral oil composition of improved viscosity, pour depressing and detergent-dispersant properties and concentrates thereof comprising between about 10 and 95 wt. % mineral oil of a lubricating viscosity and between about 0. 1 and 90 wt. % of said complex product.
