摘要： 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.

摘要： 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.
