Patent number: 7579427Abstract: A new series of wholly aromatic poly(arylene ether ether ketone ketone)s containing pendant sulfonic acid groups (SPAEEKK) were conveniently prepared by potassium carbonate mediated nucleophilic polycondensation reactions of inexpensive commercially available monomers: 1,3-bis(4-fluorobenzoyl)benzene (BFBB), sodium 6,7-dihydroxy-2-naphthalenesulfonate (DHNS), and 4,4?-biphenol or hydroquinone in N-methyl-2-pyrrolidone (NMP) at 170° C. FT-IR and NMR were used to characterize the structures and the sulfonate or sulfonic acid contents (SC) of the polymers. Flexible membrane films were obtained by casting N,N-dimethylacetamide (DMAc) solutions of copolymers. Membrane films in acid form were then obtained by treating the sodium form membrane films in 2 N sulfuric acid at room temperature. Glass transition temperatures (Tgs) and decomposition temperatures (Tds) of SPAEEKKs in both sodium and acid forms were determined. Water uptake and swelling ratio values increased with SCs and temperatures.Type: GrantFiled: June 29, 2005Date of Patent: August 25, 2009Assignee: National Research Council of CanadaInventors: Yan Gao, Michael D.

Patent number: 7169191Abstract: A novel synthetic aluminium tanning agent as an alternative for chromium based tanning salts without using formaldehyde was prepared by using aromatic polymeric matrix and aluminium (III) salts as raw materials with suitable masking agents. The preparation of the syntan consists of sulphonation of aromatic molecule, which is incorporated with a polymeric network along with ligands specially designed for the complexation of aluminium (III) salts. The complex can be used as a self-tanning agent in leather industry with fairly good filling behavior. The tanned leathers exhibit shrinkage temperature about 85° C. Due to the higher precipitation point of the product, it can be used for tanning directly after deliming thus eliminating the pickling process. This product, unlike the conventional phenol based products, does not undergo photo-oxidation thereby preventing the discoloration of the tanned leathers.Type: GrantFiled: March 20, 2003Date of Patent: January 30, 2007Assignee: Council of Scientific and Industrial ResearchInventors: Mookandi Kanthimathi, Palanisamy Thanikaivelan, Jonnalagadda Raghava Rao, Balachandran Unni Nair, Thirumalachari Ramasami

Patent number: 4800118Abstract: A light stabile composition for imparting stain resistance to polyamide fiber-containing textile articles (e.g. nylon, wool or silk carpets) comprises a halogenated (e.g. brominated or chlorinated) aryl group-containing product of the condensation polymerization of a hydroxyaryl sulfonic acid (e.g., para-hydroxyphenyl sulfonic acid), a dihydroxydiaryl sulfone (e.g., dihydroxydiphenyl sulfone) and an aldehyde (e.g., formaldehyde). The polyamide fiber-containing textile articles are converted to a stain resistant product by containing the fibers with an acidified aqueous solution of the aforesaid composition.Type: GrantFiled: November 4, 1987Date of Patent: January 24, 1989Assignee: West Point PepperellInventors: John W. Reed, Richard D. Smith

Patent number: 4698401Abstract: A polyfunctional reaction product having functional phenolic OH groups is made available by reacting a phenol and an alkoxylated amino-aldehyde condensation product in the presence of a solvent and of an acid catalyst. This method makes it possible to prepare a polyfunctional phenolic reaction product which is soluble in organic solvents at a low ratio of phenolic OH groups to alkoxy groups without gelling. The reaction product is particularly useful as a curing agent for epoxy resins.Type: GrantFiled: September 9, 1985Date of Patent: October 6, 1987Assignee: The Dow Chemical CompanyInventors: Dieter H. Klein, Raymond Koenig
