Abstract:
The present invention is directed to a waterborne polymer composition having an average particle size of less than 70 nm which is prepared as an emulsion containing one or more monoethylenically unsaturated monomer, a sulfopolyester, water, and an initiator. The waterborne polymer composition is useful in size compositions for slasher dyeing of textiles to provide fibrous articles with excellent yarn abrasion resistance, blocking, water resistance, wet fastness/bleeding, and dry and wet crock resistance. In addition, the waterborne polymer composition is useful in formulations for cleaning and protecting hard surfaces.
Abstract:
A water-based ink composition is described. The ink composition contains a pigment and a polymer latex. The polymer latex may be a polymeric (polyamino) enamine latex or a mixture of a polymeric (polyamino) enamine latex and an acetoacetoxy-functional polymer latex. The inks are particularly useful as laminating and surface-printing inks. Methods of printing are also described.
Abstract:
Surfactant-containing acetoacetoxy-functional polymers (SAAPs) are described. The acetoacetoxy-functional polymer may be a surfactant-containing enamine-functional polymer and more preferably a surfactant-containing, polymeric (polyamino)enamine (PPAE). The PPAE is the reaction product of a surfactant-containing acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The polymers may be prepared as waterborne polymer compositions, such as latexes. The waterborne polymer compositions can be prepared with high solids content while maintaining low viscosity. Waterborne polymer compositions containing the polymers of the inventions are useful in a variety of coating formulations such as, for example, paints, inks, sealants, and adhesives. When used in coating formulations, the polymers of the invention provide adhesion and crosslinking in the final film or coating. The film or coating may be cured at ambient temperatures or may be thermally cured.

Abstract:
A melt extrusion composition made by combining about 99.9 to about 98.5 weight percent of at least one polyester and about 0.1 to about 1.5 weight percent additive provides for a polyester or copolyester non-circular cross sectional fiber having at least four percent improved shape retention as compared to the same fiber made from a melt extrusion composition without the additive. The additive is present at the air-polymer interfacial surface during melt spinning. A method of making the fiber is also disclosed.
Abstract:
Disclosed is a process for the conversion of off-color cyclopropanecarboxylic acid (CPC-Acid) to CPC-Acid having a color value (platinum-cobalt scale) of less than 10 by the steps of: (1) heating off-color CPC-Acid produced by the oxidation of cyclopropanecarboxaldehyde with molecular oxygen with a strong acid; and (2) distilling the mixture of step (1) to obtain CPC-Acid having a color value of less than 10 as the distillate product.

Abstract:
The present invention provides a process comprising the steps of a) melt reacting at least one glycol and at least one dicarboxylic acid to form a polyester having an IhV of at least about 0.5 dl/g, wherein said at least one glycol is selected from the group consisting of glycols having up to 10 carbon atoms and mixtures thereof and said dicarboxylic is selected from the group consisting of alkyl dicarboxylic acids having 2 to 16 carbon atoms, aryl dicarboxylic acids having 8 to 16 carbon atoms and mixtures thereof; and b) forming said polyester into shaped articles directly from step a). Thus, the present invention provides a direct melt to mold process for forming polyester articles.
Abstract:
A solid, air stable adhesive composition containing wax and a polyolefin having a viscosity no greater than 2,000 centipoise and a needle penetration hardness of at least 50 dmm is disclosed. It is further disclosed that propylene-ethylene copolymer is the preferred polyolefin of the present invention.
Abstract:
A laminar flow process for preparing cellulose diacetate fibers is disclosed. In the process, a precipitation-acid stream and acid-dope stream are contacted in a zone having substantially laminar flow. The acid-dope stream is annularly disposed within and flows in the same direction as the precipitation-acid stream. The precipitation-acid stream has a temperature of 100 DEG to 200 DEG F and comprises 25 to 35 percent by weight acetic acid and 75 to 65 percent by weight water. The acid-dope stream has a temperature in the range of 100 DEG to 200 DEG F and comprises 5 to 22 weight percent of cellulose diacetate having an inherent viscosity of at least 1.0, and 95 to 78 percent by weight of a mixture comprising 65 to 90 weight percent acetic acid and 35 to 10 weight percent water. The precipitation-acid stream has a linear flow greater than or equal to the linear flow of the acid-dope stream. The weight ratio of the precipitation-acid stream to the acid-dope stream is at least 9:1. Contacting the two streams in this manner causes precipitation of cellulose diacetate fibers of predictable diameter as the two streams diffuse together.
