The present invention relates to new alkaline, preferably highly alkaline, cleaning solutions comprising surfactants with improved stability and cleaning performance under such conditions. It further relates to novel surfactants.

Highly stable and alkaline cleaning solutions and soluble surfactant

Compositions containing surfactant compounds according to formula (I)ROCHCH(OH)CRRZR&#x2003;&#x2003;(I)wherein Z is S, SO, or SO, can have a range of equilibrium and/or dynamic surface tensions and a range of foaming performance attributes, depending upon the particular values of Z, R, R, R, and R. The compounds of formula (I) may be prepared by a process that includes reaction of a thiol with a glycidyl ether.

2-Hydroxy-3-alkoxypropyl sulfides, sulfones, and sulfoxides: new surface active agents

Compositions containing surfactant compounds according to formula (I)ROCHCH(OH)CRRZCRRCH(OH)CHOR,&#x2003;&#x2003;(I)wherein Z is S, SO, or SO, can have a range of equilibrium and/or dynamic surface tensions and a range of foaming performance attributes, depending upon the particular values of Z, R, R, and R. The compounds of formula (I) may be prepared by a process that includes reaction of a sulfide source such as a metal sulfide or bisulfide with an alkyl glycidyl ether. The compounds may be useful in any of a broad range of applications requiring the use of a surfactant.

The present invention relates to novel tertiary alkanolamines useful as catalysts for preparing polyurethane foams and as additives to reduce the dynamic surface tension of aqueous solutions. The tertiary alkanolamines may be represented by formula (I):wherein A, R&#x2013;R, and n are defined herein, and where the tertiary alkanolamine is acid-blocked with a carboxylic acid.

The reaction of unsaturated carbonates such as vinyl ethylene carbonate with N-aminoethylimidazolidone (TAM) under mild conditions generates a mixture of two vinyl and hydroxy functional imidazolidone carbamates which polymerize readily into acrylate or vinyl acetate based emulsion polymers. The polymers show enhanced wet adhesion (wet scrubbability) in latex paints and coatings.

Wet adhesion monomer and derived copolymers for latex paints

Oligomers of vinyl esters, preferably of vinyl acetate, are provided in which the molecules contain a single terminal sulfonate group, thereby making these products useful as surface-active agents. These oligomers can be converted by hydrolysis to sulfonate-terminated vinyl alcohol oligomer which is also a surface-active agent. The number average molecular weight of the vinyl ester oligomer is not over 17,000 and not over 7,500 for the vinyl alcohol oligomer. These products are made by polymerizing the vinyl ester in the presence of a bisulfite chain transfer agent in water, preferably with a cosolvent such as methanol. The vinyl ester is delay fed to the polymerization, molecular weight is controlled with the bisulfite, and the system is maintained in a virtual single phase with any organic phase present swollen with water or water and cosolvent.

Sulfonate-terminated oligomers of vinyl esters and their vinyl alcohol oligomer derivatives

Amine functional polymers are prepared by polymerization of vinylamides with vinyl ester monomers. The resultant polymers are hydrolyzed under acid conditions and subsequently at least partially basified to the free-base amine. Byproduct salts are removed by precipitation or by extraction into an immiscible phase. The polymers made by this method are crosslinkable through reaction of the amine groups and are useful in high performance coatings, adhesives, binders and the like.

Synthesis of amine functional co-and terpolymers

The present invention relates to compositions of matter corresponding to the formula: ##STR1## wherein R.sub.1 through R.sub.4, inclusive, are independently selected from a hydrogen atom, a linear or branched alkyl or alkoxy group having from 1 to about 8 carbon atoms, an alkenyl group having from 2 to about 8 carbon atoms, amino, cyano or R.sub.1 and R.sub.1, R.sub.1 and R.sub.2, R.sub.2 and R.sub.3 or R.sub.3 and R.sub.4 may together form part of a cyclohydrocarbyl ring. The subject 9,9-bis(3,4-dicarboxyphenyl)fluorene dianhydrides demonstrate utility as reactants in the preparation of polyimides used in the fabrication of membranes for separating gaseous mixtures into their respective components.
