  • Patent number: 8178645
    Abstract: A polyester polyol, referred to hereinafter as a MHMS polyol comprises fatty acid based mer units wherein at least about 80 weight percent of the fatty acid based mer units are from methyl 9 (10) hydroxymethylstearate, or is prepared from an oil having fatty acids or fatty acid esters which are at least about 80 weight percent oleic acid or esters thereof and which has an average hydroxyl functionality of from 1.5 to 4. A reaction product, referred to herein after as MHMS alkoxysilane prepolymer, is produced from at least one such MHMS polyol and at least one isocyanate functional silane. This prepolymer is moisture cured to form a silylated MHMS polymer.

  • Publication number: 20070142544
    Abstract: Carpet backing for residential, commercial and recreational carpet which exhibits a tuftbind greater than 4.5 kg, ASTM D 1335, contains a polyurethane reaction product of a polyisocyanate; an active hydrogen containing compound; and a polyol reaction product. Typically, the polyol reaction product is a reaction product of a polyol and a vegetable oil and contains less than about 50 percent by weight of unreacted vegetable oil. The vegetable oil is preferably selected from palm oil, safflower oil, canola oil, soy oil, cottonseed oil and rapeseed oil. In a preferred embodiment, the vegetable oil is blown. Typically, the amount of unreacted vegetable oil in the polyol reaction product is less than about 34 weight percent. The hard segment of the resulting polyurethane reaction product constitutes at least 20 weight percent of the polyurethane reaction product. The carpet backing of the invention may be used as a precoat, a laminate or foam coating.

  • Publication number: 20050282001
    Abstract: The method forms a polyurethane article and involves dispersing polyurethane particles in a substantially aqueous liquid, mixing in a fine glass filler such as a post-consumer ground soda-lime glass, casting the filled dispersion and coalescing the particles by removing the liquid such that a polyurethane article having fused particles are formed. The polyurethane articles are useful as carpet backings.

  • Publication number: 20050182187
    Abstract: A polyurethane having enhanced properties is made from an aqueous polyurethane dispersion having therein a nonvolatile, non-reactive, property enhancing water-soluble (NNPEW) compound such as urea. Even though the NNPEW is soluble in water, the NNPEW remains in the polyurethane after being exposed to water. In another embodiment, the NNPEW may react with a compound present in the dispersion other than the polyurethane particles of the dispersion when removing the water of the dispersion to form the polyurethane or upon subsequent heating.

  • Patent number: 6514572
    Abstract: A process for preparing polyurethane films is disclosed, comprising electrodepositing the film onto a substrate from a polyurethane dispersion. One advantage of the electrodeposition process of the present invention is that there is no need for an additional step to remove coagulants from the films, as with conventional coagulation processes. Another advantage is that in using electrodeposition, the amount of water that must be removed during a dewatering step is minimized. A third advantage is that the resulting film demonstrates much greater uniformity in thickness as compare to films prepared by conventional coagulation techniques. The present invention has applicability in, for example, medical applications.

  • Patent number: 6451908
    Abstract: A process for preparing a polyurethane film comprising two steps is disclosed. The first step comprises preparing a nonionic prepolymer formulation, the prepolymer formulation comprising a diisocyanate, an active hydrogen containing material, and a monol. The second step comprises preparing an aqueous dispersion of the prepolymer, in the presence of a surfactant. Both steps occur in the substantial absence of an organic solvent. Also disclosed is a polyurethane film and an aqueous dispersion useful for preparing such films. The present invention has the advantage of having increased shear stability. The dispersions of the present invention do not settle or coagulate prematurely. Moreover, the films of the present invention do not include the dermal irritants which occur in natural rubber latex. The films and dispersions of the present invention are thus suitable for use in applications such as, for example, medical applications.

  • Publication number: 20020002227
    Abstract: A process for preparing an anti-static film comprising incorporating a conductivity inducing material into a polymeric film. The conductivity inducing material is a non-volatile metal salt. The polymeric film is selected from polyurethane, polyolefins, polyvinyl chloride, nitrile rubber, polyisoprene, hydrogenated block copolymers, styrene-isoprene-styrene/styrene-butadiene-styrene block copolymers, styrene butadiene latexes, and natural rubber latex. Anti-static films and gloves prepared from such process are also disclosed.
