US Classification:

525329700

Abstract:

A process for preparing polyisocyanate-modified polycarboxylic acids by conversion of anhydride-group-free polycarboxylic acids with isocyanate-functional compounds. The process includes reacting A) an anhydride-group-free polycarboxylic-acid component with B) an isocyanate-functional component having an (average) isocyanate functionality of at least 1.8, at an equivalent ratio of carboxylic acid groups to isocyanate groups of from 1.2:1 to 120:1. The polyisocyanate-modified polycarboxylic acids are solid below 40 C. and liquid above 130 C., and have an average carboxylic acid functionality of at least 1.8, a content of free carboxylic acid groups of from 4.0 wt. % to 80.0 wt. % and a content of amide groups of from 0.4 wt. % to 32.5 wt. %.

Appl. No.:

12/047450

Inventors:

James W. Rawlins - Petal MS, US
Huaxiang Yang - Hattiesburg MS, US
Sharathkumar K. Mendon - Hattiesburg MS, US

International Classification:

C08G 18/81
C08K 3/20

US Classification:

523201, 528 45

Abstract:

The present invention provides a nanocapsule of a blocked isocyanate encapsulated within a polymeric nanosphere. In one aspect, the polymeric nanosphere is functionalized. Free isocyanate functionality is released upon thermal annealing or UV exposure of the nanospheres containing the blocked isocyanate. This present invention also provides a novel method for encapsulating isocyanates in aqueous media. In one aspect, the method comprises miniemulsion polymerization. The thermally or UV deblocked isocyanate can be used as an active functional group for many potential applications.

Abstract:

Disclosed herein are polymeric materials such as a coating, a plastic, a laminate, a composite, an elastomer, an adhesive, or a sealant; a surface treatment such as a textile finish or a wax; a filler for such a polymeric material or a surface treatment that includes an enzyme such as an esterase (e.g., a lipolytic enzyme, a sulfuric ester hydrolase, an organophosphorus compound degradation enzyme), an enzyme (e.g., a lysozyme, a lytic transglycosylase) that degrades a cell wall and/or a cell membrane component, a biocidal or biostatic peotide, and/or a peptidase. Also disclosed herein are methods of altering a material's property such as service life, flexability, or rigidity, by incorporation of an enzyme into a material capable of being chemically crosslinked by the activity of a lipolytic enzyme, a hydrolase, and/or a urease.
