摘要:
Novel halogenated organoaluminum catalysts are prepared by prereacting a material of the formula:R.sub.m AlX.sub.3-mWherein m is an integer of from 1 to 3 inclusive, R is the same or different alkyl radical of straight or branched chain structure of from 1 to 7 carbons and X is the same or different halogen selected from the group consisting of chlorine and bromine with Y moles of halogen, halogen acid, mixed halogen or organo-halide per mole of aluminum compound wherein the halogen is selected from the group consisting of chlorine and bromine and the organo group is an alkyl group of straight or branched chain structure of from 2 to 20 carbon atoms, an allylic group of 3-20 carbon atoms or a benzylic group of 7-20 carbon atoms, the quantity (Y) being selected such that (m-Y) is from less than 0.7 to about 0.2. The materials must be prepared sufficiently prior to use to insure extensive reaction of the components to yield an effective polymerization catalyst. Preferably, the components are prereacted for at least 2 minutes, more preferably, at least 10 minutes, most preferably at least 4 hours, i.e. (overnight). The catalyst is prepared at any temperature insuring liquid conditions, i.e., -100 .fwdarw.+100.degree. C depending on the components selected for reaction, ambient temperature being most convenient.The compounds are useful as hydrocarbon soluble catalysts and are prepared sufficiently in advance of use to insure complete reaction between the two components yielding the reactive entity. The novel soluble catalysts frequently exhibit higher catalytic activity and efficiency than those of the prior art. They permit polymerization reactions to be run which yield higher molecular weight polymers and copolymers at higher temperatures. The catalysts of the instant invention are particularly useful in the synthesis of highly unsaturated isoolefin multiolefin copolymers of high molecular weight.
摘要:
The present invention is based on the discovery that viscosification agents selected from sulfonated and neutralized sulfonated ionomers can be readily incorporated into oil-based drilling muds in the form of an oil soluble concentrate containing the polymer. Thus, one embodiment of the present invention provides an additive concentrate for oil-based drilling muds comprising a drilling oil, especially a low toxicity oil, and from about 5 gm to about 20 gm of sulfonated or neutralized sulfonated polymer per 100 gm of oil. Indeed, oil solutions obtained from the sulfonated and neutralized sulfonated polymers used as viscosification agents are readily incorporated into drilling mud formulations.

The additives comprise the reaction product of a functionalized 1-butene copolymer and at least one nucleophilic reactant selected from amines, amino alcohols, alcohols, and reactive metal compounds. The functionalized copolymer has within its structure at least one acyl functional group selected from the group consisting of C.sub.4 to C.sub.10 dicarboxylic acids and derivatives thereof and C.sub.3 to C.sub.10 monocarboxylic acids and derivatives thereof. The 1-butene copolymer is derived from 1-butene and at least one other .alpha.-olefin of formula CH.sub.2 .dbd.CHR', wherein R' is methyl or a C.sub.3 to C.sub.12 linear or branched alkyl group. The copolymer has a number average molecular weight of at least about 700, a molecular weight distribution of less than 5, and ethenylidene groups terminating at least about 30% of all polymer chains. The dispersant additives are useful in oleaginous compositions including lubricating oil compositions and concentrates and fuel compositions.
