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

Publication number: 20040259996Abstract: The present invention relates to high-viscous moulding materials on basis of thermoplastic polymers from the group consisting of polyamides, polyesters, polyether esters, polyester amides or mixtures thereof and nano-scale fillers, i. e. fillers having a medium particle size in the range of smaller than 1 &mgr;m. The moulding materials according to the present invention have an increased melt strength as well as an advantageous balanced mechanical property profile even at elevated temperature and are used for the production of moulded articles, hollow bodies, semi-finished products, plates and pipes.Type: ApplicationFiled: August 22, 2003Publication date: December 23, 2004Inventors: Georg Stoppelmann, Ralph Kettl

Publication number: 20040254285Abstract: A fiberglass non-woven binder composition containing a carboxy-functional copolymer binder crosslinker and a compound capable of forming a hydrogen-bonding complex with the carboxy-functional copolymer binder. The binder composition provides a strong, yet flexible bond that allows a compressed fiberglass mat to easily expand once the compression is released. The binder composition is capable of being cured at lower cure temperatures than those binders prepared using conventional crosslinkers.Type: ApplicationFiled: June 3, 2004Publication date: December 16, 2004Inventors: Klein A. Rodrigues, Daniel B. Solarek
