Patent number: 6869989Abstract: Disclosed is a process for modifying cashew nut shell liquid (CNSL) which involves the steps of subjecting the CNSL to ozonolysis to form ozonolysis reaction products, followed by reduction of the ozonolysis reaction products to give a mixture of phenolic components and aldehydes. In a preferred embodiment, the process involves reacting CNSL with ozone to form a mixture containing ozonolysis reaction products, and then treating the mixture under reducing conditions to form a further mixture containing phenolic components with an eight carbon chain having a terminal —CHO group and alkyl components of varying lengths with either one or two terminal —CHO groups. The resulting CNSL aldehydes may be used to form adhesives for use in the manufacture of composites such as wood particle board.Type: GrantFiled: May 25, 2001Date of Patent: March 22, 2005Assignee: Cambridge Biopolymers LimitedInventors: Mohammed Lokman Khan, Jeremy Tomkinson, Richard James Salisbury

Patent number: 6835764Abstract: This invention relates to a composition which can be used to form a wood substitute. The composition comprises 30 to 70% (volume by volume) of a high molecular weight aliphatic polyester and comminuted cellulose-containing plant material, wherein the aliphatic polyester comprises 1,4-butanediol condensed with adipic acid and/or succinic acid. The invention also provides for producing wood substitute from the composition. The wood substitute has characteristics of natural wood. Articles made from the wood substitute are biodegradable and do not give off toxic fumes when combusted.Type: GrantFiled: January 13, 2003Date of Patent: December 28, 2004Assignee: Bio-Deg. Moulding Pty LtdInventors: Richard Anthony Leckey, Allan Leon Sydney Hill, Alan John Reichle

Patent number: 6787245Abstract: Sulfonated aliphatic-aromatic copolyesters are provided. The copolyesters are produced from a mixture of aromatic dicarboxylic acids, aliphatic dicarboxylic acids, ethylene glycol, other glycols, and components containing alkali metal or alkaline earth metal sulfo groups, such as a metal 5-sulfoisophthalic acid derivative. The copolyesters have lower sulfonation than known sulfonated polyesters, and provide advantageous thermal properties for some end uses. The sulfonated aliphatic-aromatic copolyesters are useful in forming coatings or films on various substrates, and in packaging. Some compositions comprising the sulfonated aliphatic-aromatic copolyesters are biodegradable, as are some of the sulfonated aromatic-aromatic copolyesters.Type: GrantFiled: June 11, 2003Date of Patent: September 7, 2004Assignee: E. I. du Pont de Nemours and CompanyInventor: Richard Allen Hayes

Patent number: 6787590Abstract: This invention relates to novel composites comprising plastic and plant material derived from members of Parthenium spp. and, in particular, Parthenium argentatum (also known as guayule), Parthenium tomentosum or Parthenium incanum. The invention is also directed to composites that possess insect, fungal, and microbial resistance. Products made from composites of the instant invention are useful to make numerous items, particularly those used for construction such as lumber, plywood, particleboard, fiberboard, poles, railroad crossties, or the like.Type: GrantFiled: April 5, 2001Date of Patent: September 7, 2004Assignees: The United States of America as represented by the Secretary of Agriculture, The Board of Trustees of the University of IllinoisInventors: Francis S.
