  • Patent number: 6111146
    Abstract: The invention is a new family of non-ionic surfactants and a method of making same. The surfactants are made by (1) alkoxylating an alkylphenol with an alkylene oxide using a standard alkylene catalyst; (2) hydrogenating the alkoxylated alkylphenol until it is either fully or partially saturated using selective catalysts such that the aromaticity of the compound is eliminated; (3) if necessary, further alkoxylating the resulting non-aromatic molecule. The resulting compound is an alkylcyclohexanol alkoxylate possessing excellent surfactant properties for use as a emulsifiers, for wetting and penetration, for scouring, and general surface modification.

  • Patent number: 4929769
    Abstract: A halogenated polyether is provided having a chemical structure which has been found to possess the requisite characteristics for satisfactory service as a promoter of good adhesion between a polymeric surface (e.g., a polyethylene terephthalate tire cord) and an elastomeric material (e.g., rubber). The halogenated polyether may be formed by (1) the reaction of an organic polyhydroxy compound with epihalohydrin (e.g., epichlorohydrin) to create ether linkages, (2) the epoxidation of the ends of the ether chains which extend from the residual portion of the organic polyhydroxy compound, and (3) the substantial hydrolysis of the epoxy groups (as described). The resulting halogenated polyether is substantially free of epoxy groups, contains at least one 2-halomethyloxyethylene unit, and contains 2,3-dihydroxypropyl end groups (as described). Such halogenated polyether optionally may be provided in the form of an oligomer (as described).

  • Patent number: 4867750
    Abstract: The invention relates to a polymer having the structure ##STR1## and mixtures thereof wherein R is a perhalogenated aromatic or cyclo aliphatic radical containing from 6 to 7 carbon atoms in the cyclic structure; R.sup.1 is hydroxy or C.sub.1 to C.sub.10 alkoxy; R.sup.2 is hydrogen or C.sub.1 to C.sub.10 alkyl; EO represents the radical --CH.sub.2 CH.sub.2 O--; PO represents the radical ##STR2## m is an integer having a value of from 6 to 20; and x, y, z, x', y' and z' each represent an integer having a value of from 0 to 50 with the proviso that the sums of x+y+z and of x'+y'+z' are greater than 5.The application is also directed to the preparation and use of the above polymer.

  • Patent number: 4787989
    Abstract: The present invention relates to a class of compounds which have superior soil release properties over heretofore known soil release polymers. The compounds are prepared by the reaction of an aromatic hydroxy containing polyester soil release agent with trimellitic anhydride under acid catalysis to produce an aromatic terminal capped carbonyloxy soil release polymer.
