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

This invention provides water-based compositions, particularly coating, ink, adhesive, fountain solution and agricultural compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of a surface tension reducing amount of a mixture of a non-fluorinated anionic compound and a non-fluorinated weak base cationic compound, the mixture demonstrating a dynamic surface tension (DST) which is less than the DST of the individual anionic and cationic compounds and less than 45 dynes/cm, at a concentration of &#x2266;5 wt % in water at 23&#xb0; C. and 20 bubbles/second or less than 40 dynes/cm at a concentration of &#x2266;0.03M in water at 23&#xb0; C. and 0.1 bubbles/second according to the maximum-bubble pressure method.

Cationic-anionic blends for dynamic surface tension reduction

An MDI/polypropylene polyether prepolymer composition consisting essentially of at least 80 wt % perfect prepolymers and less than 2 wt % free MDI monomer suitable for use in polyurethane adhesive compositions optionally also comprising a curative for isocyanate groups.

MDI-based polyurethane prepolymer with low monomeric MDI content

A structural polyurethane adhesive composition comprising a polyurethane reaction product and a curative for isocyanate groups, characterized in that the polyurethane reaction product consists essentially of at least 80 wt % perfect prepolymers and less than 2 wt % free isocyanate monomer.
