Abstract: In accordance with the present invention, there is provided a novel composition of matter having the formula: ##STR1## wherein R.sub.a, R.sub.b, R.sub.c, R.sub.d and R.sub.e are independently selected from the group consisting of H, alkyl groups and substituted alkyl groups having about 1 to 10.sup.6 carbon atoms, alkenyl groups and substituted alkenyl groups having about 3 to 10.sup.6 carbon atoms, wherein the substituents on the alkyl and/or alkenyl groups are selected from the group consisting of alkoxy, halogen, CN, OH, HO(CH.sub.2 CH.sub.2 O).sub.x (X=1-10), acyl, acyloxy and aryl substituents.

Abstract: A deactivated reforming catalyst comprising a type L zeolite containing a Group VIII noble metal may be regenerated and have enhanced dispersion by a method involving contacting the catalyst with oxygen and water at elevated temperatures, contacting the catalyst at elevated temperatures with a source of chlorine such as HCl or Cl.sub.2, and preferably oxygen and water, contacting the catalyst at elevated temperatures with oxygen and optionally water, and contacting the catalyst at elevated temperatures with hydrogen and optionally water to reduce the catalyst. Preferably the noble metal is platinum.

Abstract: Zeolite L with flat basal planes, and reduced crystallite size is prepared in a synthesis modified by the addition of small amounts of additional metal such as magnesium, calcium, barium, cobalt, zinc, chromium, manganese or nickel. The addition of these metals also suppresses unwanted zeolite W formation even when the synthesis would otherwise form this zeolite.

Abstract: There are disclosed macrocyclic and polycyclic polyamine lubricating oil additives formed by cyclodehydration of reaction products of hydrocarbon substituted succinic anhydrides or carboxylic acids with poly 3-amino propyl compounds or by acylation of macrocyclic polyamines and polycyclic polyamines with hydrocarbon substituted succinic anhydride or carboxylic acids. These compounds are useful as dispersants and dispersants-V.I. improvers in both gasoline and diesel engine lubricating oil compositions and are also useful fuel additives.

Abstract: The reaction cycle time for the copolymerization of unsaturated esters such as alkyl fumarates and vinyl acetate, and for the polymerization of methacrylates and acrylates may be dramatically reduced by carrying out the polymerization at elevated temperatures and pressures. An additional feature is the addition of initiator during polymerization which leads to improved products especially for lubricating oil pour depressants and fuel and crude oil flow improvers.

Abstract: A process for halogenating polymers by contacting a polymer either in solution or in bulk with a halogenating agent in the presence of an acid scavenger. Halogenated polymer, e.g., butyl rubber, with a particular structure is obtained and the product suffers less molecular weight loss. Combinations of acid scavengers can also be used and the scavenger can be dispersed in the polymer prior to halogenation and/or added to the reaction zone during halogenation.

Abstract: Improved stability of overbased phenates, particularly when formulated with overbased sulphonates, as well as improved foaming tendency and viscosity is obtained by treating the overbased phenate, either during or subsequent to the overbasing process, with from 0.1 to 10 wt. %, preferably 2 to 6 wt. %, of a carboxylic acid with a C.sub.10 to C.sub.24 unbranched segment, e.g. behenic acid.

Abstract: A water soluble polymer which is characterized by the formula: ##STR1## wherein x is 50 mole percent or 662/3 mole percent or 75 mole percent and y+z is 50 mole percent, when x is 50 mole percent, y+z is 331/3 mole percent, when x is 662/3 mole percent, and y+z is 25 mole percent, when x is 75 mole percent, wherein the molar ratio of y to z is about 100:1 to 1:100, and M.sup.+ is hydrogen or a metal cation selected from the group consisting of lead, aluminum, iron and Groups IA, IIA, IB and IIB of the Periodic Table of Elements and the level of sulfonation based upon the styrene monomer is about 75 to about 100 mole percent.
