  • Patent number: 7341985
    Abstract: Compositions containing surfactant compounds according to formula (I) R4OCH2CH(OH)CR2R3ZR1 ??(I) wherein Z is S, SO, or SO2, 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, R1, R2, R3, and R4. The compounds of formula (I) may be prepared by a process that includes reaction of a thiol with a glycidyl ether.

  • Publication number: 20070287808
    Abstract: The present invention provides polyamide curing agent compositions comprising the reaction products of (1) multifunctional amines of structure 1 where R1 is CH2CH2CH2NH2; R2, R3 and R4 independently are H or CH2CH2CH2NH2, and X is CH2CH2 or CH2CH2CH2 with (2) dimer fatty acids, optionally in combination with monofunctional fatty acids. The curing agent compositions are useful for crosslinking epoxy resins to produce coatings, adhesives, floorings, composites and other articles.

  • Patent number: 7279447
    Abstract: Compositions containing surfactant compounds according to formula (I) ROCH2CH(OH)CR1R2ZCR1R2CH(OH)CH2OR,??(I) wherein Z is S, SO, or SO2, 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, R1, and R2. 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.
