Filed:

Jul 12, 2006

Appl. No.:

11/457069

Inventors:

Julia Elizabeth Rice - Sunnyvale CA, US
Peter Schwarz - San Jose CA, US
Yu Deng - White Plains NY, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/30

US Classification:

707 7, 707101, 707 6

Abstract:

A generalized axiomatic definition of information-theoretic similarity is provided for taxonomies that are structured as directed acyclic graph form which multiple terns may be used to describe an object. The definition is adaptable in the presence of ambiguity, as introduced by an evolving taxonomy or classifiers with imperfect knowledge, and two new similarity measures are introduced based on the definitions. A pragmatic implementation is also provided for similarity measures that arc tightly integrated with an object-relational database and scales to large taxonomies and large datasets.

International Classification:

C08J 11/04

US Classification:

521 485, 521 40, 521 48, 5283081, 528480, 528495, 502167, 502200, 564225

Abstract:

A method comprises forming a reaction mixture comprising a terephthalate polyester, a glycol comprising 2 to 5 carbons, and an amidine organocatalyst; and heating the reaction mixture at a temperature of about 120 C. or more to depolymerize the terephthalate polyester, thereby forming a terephthalate reaction product comprising a monomeric dihydroxy terephthalate diester; wherein the terephthalate reaction product contains terephthalate oligomers in an amount less than the amount of terephthalate oligomers that would result from i) substituting the amidine organocatalyst with an equimolar amount of a guanidine catalyst and ii) depolymerizing the terephthalate polyester under otherwise identical reaction conditions.

International Classification:

C08G 63/08
C08G 67/00

US Classification:

528354, 528271

Abstract:

Methods to form a polymer by ring-opening polymerization include reacting, a mixture comprising a monomer, an accelerator, an initiator, and a catalyst comprising a 1,1,1,3,3,3-hexafluoropropan-2-ol-2-yl group to form the polymer. Also disclosed are polymers including a residual amount of the catalyst in an amount greater than 0 weight percent.
