    Abstract: Copolymers comprising recurring units of a phenyl glycidyl ether and alkylene oxides are disclosed. Some of the copolymers comprise a di- or polyfunctional nucleophilic initiator and recurring units of the phenyl glycidyl ether and an alkylene oxide. The di- or polyfunctional nucleophilic initiator is an alcohol, phenol, amine, thiol, thiophenol, sulfinic acid, or deprotonated species thereof. Other copolymers comprise a monofunctional nucleophilic initiator selected from thiols, thiophenols, aralkylated phenols, sulfinic acids, secondary amines, C10-C20 terpene alcohols, and deprotonated species thereof. Pigments dispersions comprising the copolymers are also disclosed. The copolymers meet the growing needs of the industry with their ease of manufacture, diverse structures, and desirable performance attributes for dispersing a wide range of organic and inorganic pigments. Agricultural applications for the copolymers are also disclosed.

    Abstract: A method for boosting the high-temperature blocking resistance of a cured coating made from a waterborne coating formulation is disclosed. Blocking resistance is boosted by incorporating an additive which comprises an organoamine salt of a non-ethoxylated C4-C15 alkyl phosphate. Also disclosed are waterborne coating formulations and cured coatings produced from the formulation. The coating formulations comprise an acrylic latex, water, a dispersant, a pigment, and the anti-blocking additive. Surprisingly, the organoamine salts demonstrate good wetting properties as well as improved high-temperature blocking resistance, much better water solubility, and easier handling when compared with the corresponding alkali metal or ammonium salts. The additives are cost effective and offer environmental and recoating advantages when compared with the fluorochemicals currently available as anti-blocking additives.

    Abstract: Mixed dimer and mixed oligomer compositions are disclosed. The mixed dimer compositions comprise a monosulfonated cross-dimer or a salt thereof. The monosulfonated cross-dimer is a reaction product of (a) an alpha-olefin sulfonic acid (AOS acid); and (b) an unsulfonated olefin, an unsulfonated olefin precursor, or a functionalized olefin. The mixed oligomer compositions comprise a mono- or polysulfonated cross-oligomer or a salt thereof. The mono- or polysulfonated cross-oligomer is a reaction product of (a) an AOS acid; and (b) an unsulfonated diolefin or an unsulfonated diolefin precursor. Various methods for making the mixed dimer or oligomer compositions are described. Salts of the mixed dimer and oligomer compositions are useful surfactants for foams used in oilfield and other applications. The foams have improved high-temperature stability when compared with foams from AOS dimer acid salts.

    Abstract: Dilutable concentrates useful for hard surface cleaners with improved film/streak performance on high-energy surfaces are disclosed. The concentrates comprise a nonionic alkoxylated surfactant and a polyetheramine. A relatively minor proportion of a polyetheramine can resolve film/streak issues that characterize hard surface cleaners formulated with nonionic surfactants. The efficacy of polyetheramines for improving film/streak performance of hard surface cleaners formulated with nonionic alkoxylated surfactants far exceeds the benefits available from known improvements, such as the use of hydrotropes. Other inventive dilutable concentrates and hard surface cleaners comprise an amine-functional hydrophobe and an auxiliary surfactant. Still other dilutable concentrates or hard surface cleaners comprise a nonionic alkoxylated surfactant and lactic acid. An improved method for measuring film/streak properties of hard surface cleaners is also disclosed.

    Abstract: Methods of making an alpha-olefin sulfonic dimer acid (AOS dimer acid) are disclosed. In one method, an alpha-olefin is sulfonated, preferably with sulfur trioxide, to produce a mixture comprising an alpha-olefin sulfonic acid (AOS acid) and sulfur dioxide. This mixture is then heated while purging sulfur dioxide and hydrogen sulfide from the reactor to produce an AOS dimer acid composition. In another method, the AOS acid mixture is treated to remove sulfur dioxide and is then heated to produce an AOS dimer acid composition. With either method, the resulting AOS dimer acid composition has at least a 30% decrease in the level of elemental sulfur when compared with that of an AOS dimer acid composition prepared by a similar process in the absence of any active removal of sulfur dioxide or hydrogen sulfide. AOS dimer acid compositions and salts of the AOS dimer acids, which are useful surfactants for oilfield and other applications, are also disclosed.
