Abstract: A catalyst precursor of the formula: ##STR1## wherein: L is a cycloalkadienyl ligand;W, X, Y, and Z are independently hydrogen, a hydrocarbyl group containing 1 to 20 carbon atoms, or a silyl group, and may be connected to L through a bridging group comprising at least two Group IVA atoms; with the proviso that one of X, Y, and Z is a negative charge stabilizing group selected from the group consisting of Group IVA trialkyl groups, aryl groups, heteroaromatic groups, ethylenically unsaturated hydrocarbon groups, acetylenically unsaturated hydrocarbon groups, ketonic groups, and aromatic organometallic moieties, is provided. When combined with a compound comprising a metal from Groups IIIB to VIII or the Lanthanide series of the Periodic Table of elements and an activating cocatalyst, the catalyst precursor is useful for the polymerization of olefins.

Abstract: Gelators gel a variety of nonpolar and polar liquids. Moreover, gelation of various monomers with subsequent polymerization of the gelled monomers forms organic zeolites and membrane materials. An ionic gelator includes salts of compounds of the formula (I):?R.sup.1 R.sup.2 R.sup.3 X-R.sup.4 !.+-.Y.-+. (I)where R.sup.1, R.sup.2 and R.sup.3 are the same or different hydrogen or organic groups including alkyl groups, alkenyl groups, alkynyl groups, aryl groups, arylalkyl groups, alkoxy groups, aryloxy groups; X is a Group IIIA or Group VA element; R.sup.4 is a steroidal group, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an arylalkyl group, an alkoxy group or an aryloxy group; and Y is a Group IA or Group VIIA element or one-half of a Group IIA or VIA element, that is, a divalent counterion. The gelling agent composition may include a single isomer or mixtures of isomers of the formula (I). A non-ionic gelator also includes compounds of the formula:R.sup.1 R.sup.2 R.sup.3 X (II)where R.

Abstract: A gelling composition and a process for using the gellimg composition for oilfield applications are provided. The gelling composition comprises a water-soluble polymer, a crosslinking agent, and a liquid wherein the water-soluble polymer comprises repeat units derived from a nitrogen-containing olefinic monomer and optionally an olefinic comonomer. The gelling composition can be used in drilling fluids, workover fluids, completion fluids, permeability corrections, water or gas coning prevention, fluid loss prevention, matrix acidizing, fracture acidizing, and combinations of any two or more thereof.

Abstract: A dispersible ionic catalyst activator, comprising an insoluble substrate material having a correlated settling rate less than 0.03 cm/sec, and from 0.001 to 10 mmol/g of an ionic catalyst activator deposited thereon which is particularly adapted for use in a continuous, solution polymerization process.

Abstract: An improved method is provided for copolymerizing vinyl chloride with allyl glycidyl ether and a vinyl ester. The copolymers so formed include 70-99 weight % of vinyl chloride, 0.05-15 weight % of allyl glycidyl ether, and 0.05-15 weight % of a vinyl ester, preferably vinyl acetate. The copolymers of this invention can be compounded to provide films exhibiting improved heat stability, low haze, and good adhesion to solid surfaces such as glass and metal. The compounded resins thus obtained may be especially advantageously used in forming the interlayer of laminated safety glazings, such as vehicle windshields and architectural glazings.

Abstract: An aqueous polymer composition comprising 10 to 40 wt % of a polymer in water, the polymer consisting essentially of 20-90 wt % .alpha.,.beta.-ethylenically unsaturated carboxylic acid monomer, 10-80 wt % one or more softening monomers, the aqueous composition being adjusted to pH 4-6 with alkali metal hydroxide or alkaline earth metal hydroxide and further containing 0.1 to 3 wt % zirconium crosslinking salt. Such aqueous compositions can be applied to nonwoven and woven substrates to make superabsorbent products.

Abstract: Low viscosity, fast curing binders for nonwoven cellulosic materials comprise an aqueous dispersion of discrete particles of a highly functionalized emulsion copolymer resulting from the copolymerization of a water insoluble olefinic non-ionic organic compound, a water soluble olefinic carboxylate compound and a water soluble olefinic hydroxy ester or a water soluble olefinic amide or a mixture of hydroxy ester and amide. The emulsion copolymer dispersion is admixed with a latex to provide a binder having a relatively low viscosity and capable of reaching about 80 percent of fully cured wet tensile strength in 8 seconds or less.
