Publication number: 20060083709Abstract: This invention relates to a device that provides controlled release of a fragrant or deodorizing substance: the fragrant or deodorizing substance being solublized with an appropriate carrier solvent within a polymeric matrix. The layers function as protective barriers, semi-permeable membranes, fragrance reservoirs, and adhesives. The device is capable of delivering a fragrance at a controlled rate for a prolonged period of time through the gradual diffusion and release of fragrant material carried by a solvent from a reservoir system to the semi-permeable UV curable, oligomer composition acting a fragrance release regulator. Additionally, the UV curable, oligomeric composition that forms the reservoir and regulating layer can be engineered to be adhesive through cure inhibition. The method of cure inhibition can also be utilized to create internal areas of high and low cross link density to further control the release rate of a fragrance.Type: ApplicationFiled: October 18, 2004Publication date: April 20, 2006Inventors: David Hutchings, Robert Fechter, Edward Toplikar, Raymond Harvey, Robert Cassidy, Frances Lockwood, Wen-Chen Su

Patent number: 6559203Abstract: This invention relates to an organic foundry binder containing an alkyl resorcinol, or preferably a readily available mixture of alkyl resorcinols, and derivatives thereof. Preferably, the organic foundry binder is a furan binder. Foundry mixes are prepared by mixing the binder with a foundry aggregate. Foundry shapes (molds and cores) are prepared by shaping the mix and allowing it to cure to form a workable foundry shape. The invention also relates to the preparation of metal castings using the foundry shapes and the metal castings prepared with the foundry shapes.Type: GrantFiled: February 13, 2002Date of Patent: May 6, 2003Assignee: Ashland Inc.Inventors: David A.

Process for reducing mono-functional and non-functional by-products during aralkylation of phenolics
Patent number: 6399740Abstract: Phenol aralkyistion polymers can be prepared by reaction among a phenolic monomer, at least one styrenic monomer and an aryl diolefin. A phenolic monomer can be initially aralkylated in the presence of an acid catalyst with a first portion of at least one styrenic monomer to obtain an aralkylated phenol. The aralkylated phenol thereafter can be reacted with an aryl diolefin to obtain a phenol aralkylation polymer. Optionally, (though preferably) the phenol aralkylation polymer is further aralkylated with a second portion of at least one styrenic monomer. By employing specific catalyst concentrations, reactant concentrations, reaction temperatures, and reaction times, the formation of mono-functional and non-functional by-products is substantially reduced.Type: GrantFiled: July 6, 1999Date of Patent: June 4, 2002Assignee: Georgia-Pacific Resins, Inc.Inventors: Edward Lucas, Jr., David A. Hutchings, Rajan Hariharan, Syed A. Elahi, David J. Bir -

The invention also relates to foundry mixes prepared with the binder, foundry shapes prepared with the foundry mix, and metal castings prepared with the foundry shapes.Type: GrantFiled: April 27, 2000Date of Patent: May 21, 2002Assignee: Ashland Inc.Inventors: Ken K.

Patent number: 6291077Abstract: A lactone chain-extended polyester polyol of the present invention comprises the reaction product of a lactone and a previously chain-extended phenolic-based hydroxyl compound. The previously chain-extended phenolic-based hydroxyl compound may comprise the reaction product of (i) a lactone or an alkoxylating agent selected from the group consisting of alkylene oxides and alkylene carbonates, and (ii) a phenolic aralkylation polymer comprising the reaction product of a phenolic monomer having at least two free reactive positions; a styrene derivative; and a coupling agent. The previously chain-extended phenolic-based hydroxyl compound also may be chain-extended by reacting with a lactam to produce a lactam chain-extended polyester polyamide. The polyols and polyamides of the present invention provide unique combinations of hard and soft functionalities, which translates into materials exhibiting a unique combination of toughness and hardness.Type: GrantFiled: August 28, 2000Date of Patent: September 18, 2001Assignee: Georgia-Pacific Resins, Inc.Inventors: Rajan Hariharan, David A.
