US Patent:
20110021658, Jan 27, 2011
Filed:
Oct 9, 2008
Appl. No.:
12/682267
Inventors:
Sergey Selifonov - Plymouth MN, US
Scott David Rothstein - Sauk Rapids MN, US
Douglas Alan Wicks - Plymouth MN, US
Brian Daniel Mullen - Plymouth MN, US
Tara Jane Mullen - Plymouth MN, US
Jason Douglass Pratt - Plymouth MN, US
Charles Todd Williams - Pittsburg PA, US
Chunyong (Kevin) Wu - Plymouth MN, US
Ning Zhou - St. Paul MN, US
Assignee:
SEGETIS, INC. - Golden Valley MN
International Classification:
C08K 5/1575
C07D 319/04
C07D 317/10
C07D 407/02
US Classification:
523122, 549335, 524108, 549448, 549370
Abstract:
The invention relates to polyketal compounds. The compounds are synthesized by the selective ketalization of oxocarboxylic acids, e.g. keto acids and semialdehydes, and esters thereof with tetrols and higher polyols that products two or more cyclic ketal ester moieties per molecule, wherein the cyclic ketal moieties are situated in a bis-, tris-, or polyketal conformation. The invention further relates to applications of these compounds and subsequent reactions thereof.

US Patent:
20110196129, Aug 11, 2011
Filed:
May 4, 2006
Appl. No.:
11/920456
Inventors:
Chunyong Wu - Plymouth MN, US
Jun Li - Brookline MA, US
Douglas Wicks - Plymouth MN, US
Sarah Morgan - Hattiesburg MS, US
Robert Allen Smith - Jackson MS, US
International Classification:
C08H 1/06
US Classification:
530357
Abstract:
Keratin hydratable absorbents and films are fabricated with simple, repeatable processes. Freeze drying produces a material with instantaneous water absorption to over 20 times its weight in water. Films produced are flexible and uniform with water absorption 7-8 times the original weight.

US Patent:
20120122745, May 17, 2012
Filed:
Dec 21, 2011
Appl. No.:
13/333273
Inventors:
Brian D. MULLEN - Delano MN, US
Chunyong WU - Plymouth MN, US
Tara J. MULLEN - Delano MN, US
Marc D. SCHOLTEN - Saint Paul MN, US
Vivek BADARINARAYANA - Saint Louis Park MN, US
Assignee:
SEGETIS, INC. - Golden Valley MN
International Classification:
C10M 169/04
C07D 317/30
C07D 319/06
C08K 5/1575
C09K 3/00

US Classification:
508308, 549448, 549454, 549375, 549370, 524108, 521 88, 25218228
Abstract:
Various esterified alkyl ketal ester or hydroxyalkyl ketal ester products are useful as components of organic polymer compositions. The ketal esters are produced in certain transesterifications between alkyl ketal esters and/or hydroxyalkyl ketal esters and polyols, aminoalcohols, polyamines and/or polycarboxylic acids. The products are excellent plasticizers for a variety of organic polymers, notable poly(vinyl chloride) plastisols. The products are also very good lubricants for many lubrication applications.
