Filed:

Feb 15, 2000

Appl. No.:

09/504109

Inventors:

James F. Day - Winston-Salem NC
James J. Good - Fredericksburg VA

Assignee:

Unitex Chemical Corporation - Greensboro NC

International Classification:

C07C 6976

US Classification:

560 83, 524288, 524469

Abstract:

A process for the preparation of dialkyl tetrahalophthalates. A tetrahalophthalic anhydride or acid is dissolved in excess C -C alkanols. Residual sulfuric acid is removed by treatment with magnesium acetate or multiple water washes. The mass is esterified with a tetraalkyl titanate, and residual acidic components are removed by treatment with magnesium silicate. These treatments improve processability, production cycle time, product color, clarity and purity.

International Classification:

C07C 6976

US Classification:

560 83, 252601, 252608

Abstract:

A highly flame retardant plasticized polyvinyl chloride compound (PVC) comprises a mixture of dialkyl tetrachlorophthalate and dialkyl tetrabromophthalate and is characterized by an absence of brittleness, and substantial flexibility at low temperatures as required for PVC formed jackets and insulation for wire and cable products.

Filed:

Jul 9, 2004

Appl. No.:

10/887451

Inventors:

James F. Day - Winston-Salem NC, US

Assignee:

Unitex Chemical Corporation - Greensboro NC

International Classification:

C08F 259/08

US Classification:

525276, 524507, 508465, 508478

Abstract:

A fluorochemical additive is the reaction product under polymerization conditions of monomers that include: (a) an aromatic polycarboxylic acid as an anhydride, ester, or ester chloride; (b) at least one fluorinated reactant; and (c) at least one aliphatic amine, mercaptan, or alcohol. Optionally, a crosslinking agent can be used. The components of the additive all can be viewed as contributing to the performance of the disclosed additive. The fluorine-containing component is generally insoluble in molten polymers and will tend to migrate to the cooled surface thereof where the fluorinated moieties provide repellency characteristics when used in adequate quantities, generally at least about 30 wt % depending on the fluorinated reactant used to make the additive. The aromatic component appears to facilitate solubility and speed up the orientation process of the additive within the molten polymer. The aliphatic component to the reaction mixture appears to assist in anchoring the reaction product additive in the bulk polymer structure.

Inventors:

James Day - Winston-Salem NC, US

International Classification:

C08L051/00

US Classification:

Abstract:

This invention describes hydrophobic, oleophobic, and alcohol-resistant fibers, films, and molded articles comprising synthetic organic polymer(s) in which, dispersed within the fiber, fabric or molded article are fluorochemical graft polymeric additives. Also disclosed are the additives which confer the desirable properties to the synthetic organic polymers to which they are added. The method of preparing such fibers, films and molded articles, as well as articles made therefrom, are disclosed as well.

International Classification:

D21H017/03

US Classification:

162158000, 162181100

Abstract:

A water soluble dispersant extender enhances the effectiveness and stability of hydrophobic compounds applied from aqueous solution. The invention is well suited for fluorochemical compounds applied to a substrate to impart grease and oil resistance. Exemplary substrates include paper, textiles, nonwoven, carpet and the like. The invention is also useful in firefighting foams that employ hydrophobic fluorochemical fire suppressing compounds. The present stabilizer is believed to form an inclusion complex with the hydrophobic compound whereby enhanced dispersion and solubility over the surface of the substrate allows more efficient use of the hydrophobic compound so that either less compound can be used with the same efficacy or greater efficacy is seen with the same level of active ingredient.
