    Abstract: Polymers useful in formulating dispersing agents for pigments are disclosed. One such polymer can be made from a glycidyl intermediate. A nucleophilic initiator can be reacted with epichlorohydrin to produce a glycidyl intermediate. This intermediate is reacted with an aralkylated phenol to give a hydroxy-functional hydrophobe. Alkoxylation of the hydrophobe gives the desired polymer. In an alternative, approach, the polymer is made by reacting the nucleophilic initiator with an aralkylated phenol glycidyl ether to give the hydroxy-functional hydrophobe, which is then alkoxylated. Pigments dispersions comprising the polymers are also disclosed. The polymers 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 polymers are also disclosed.

    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: Processes for making reactive surfactants are disclosed. In one such process, a fatty epoxide, a glycidyl ether, or a combination thereof is reacted with an olefin-functional nucleophile to produce an olefin-functional hydrophobe. The olefin-functional hydrophobe is reacted with ethylene oxide, propylene oxide, butylene oxides, or a combination thereof to produce an alkoxylate. Optionally, the alkoxylate is converted to the corresponding sulfate, phosphate, or maleate. Surfactant compositions comprising the reactive surfactants made by these processes are also described. The invention includes polymerizable mixtures comprising an acrylic monomer and the surfactant compositions as well as aqueous acrylic latex emulsions and coatings produced from the emulsions. The reactive surfactants deliver stable latex emulsions with reduced tendency for surfactant migration or excessive foaming. Coatings from the emulsions have improved wet adhesion, scrub resistance, and water resistance.

    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.
