Preparation Of Unsaturated Polyesters

View page
US Patent:
6555623, Apr 29, 2003
Filed:
Mar 18, 2002
Appl. No.:
10/100152
Inventors:
Lau S. Yang - Wilmington DE
Paul Malcolm Puckett - Lake Jackson TX
Lawrence J. Karas - West Chester PA
Diandre Armstead - Gilbertsville PA
Paul A. Albano - Gibbstown NJ
Assignee:
Arco Chemical Technology, L.P. - Greenville DE
International Classification:
C08L 6706
US Classification:
525168, 528302, 528306, 528308, 5283086, 525437, 525445
Abstract:
A process for making unsaturated polyesters from 2-methyl-1,3-propanediol (MPD) is disclosed. The process comprises reacting one equivalent of an aromatic diacid with about two equivalents of MPD to produce an ester diol and then reacting one equivalent of the ester diol with from about 1. 1 to about 1. 9 equivalents of maleic anhydride to produce the polyester. The polyester has a fumarate/maleate ratio of 90/10 or greater.

Vinyl Aromatic Monomer/Vinyl Phosphonate Copolymer Compositions And Foamed Articles Derived Therefrom

View page
US Patent:
51090333, Apr 28, 1992
Filed:
May 16, 1991
Appl. No.:
7/701284
Inventors:
Roger A. Grey - West Chester PA
Laurel E. Schock - Paoli PA
Diandre Armstead - Philadelphia PA
Assignee:
Arco Chemical Technology, L.P. - Wilmington DE
International Classification:
C08F23002
C08F21208
C08J 928
US Classification:
521147
Abstract:
Copolymer compositions based on vinyl aromatic monomers and derivatives of vinyl phosphonic acids are disclosed. The copolymer beads of the invention are advantageously used to make foamed articles useful for packaging and construction applications.

View page
US Patent:
51168820, May 26, 1992
Filed:
May 16, 1991
Appl. No.:
7/701279
Inventors:
Roger A. Grey - West Chester PA
Laurel E. Schock - Paoli PA
Diandre Armstead - Philadelphia PA
Assignee:
Arco Chemical Technology, L.P. - Wilmington DE
International Classification:
C08F23002
C08F21208
C08J 928
US Classification:
521147
Abstract:
A process for making thermoplastic copolymer beads from vinyl aromatic monomers and vinyl phosphonic acid derivatives is disclosed. A process for making foamed articles from the beads is also disclosed. The foamed articles are useful for packaging and construction applications.

Process For Making Pyrrolidones

View page
US Patent:
54018560, Mar 28, 1995
Filed:
Feb 28, 1994
Appl. No.:
8/202519
Inventors:
Roger A. Grey - West Chester PA
Diandre Armstead - Philadelphia PA
Assignee:
ARCO Chemical Technology, L.P. - Greenville DE
International Classification:
C07D207263
US Classification:
548552
Abstract:
A cyclocarbonylation process for making pyrrolidones under mild temperature and pressure conditions is disclosed. In the process, an allylic amine reacts with carbon monoxide in the presence of a rhodium carbonyl catalyst and an amount of a pyridine promoter effective to enhance the yield of pyrrolidone obtained in the process compared with the yield obtained in the absence of the promoter. The process can be used to make N-methyl-2-pyrrolidone from N-methylallylamine.

Process For Making .Gamma.-Butyrolactones

View page
US Patent:
54018579, Mar 28, 1995
Filed:
Feb 28, 1994
Appl. No.:
8/203163
Inventors:
Roger A. Grey - West Chester PA
Diandre Armstead - Philadelphia PA
Assignee:
Arco Chemical Technology, L.P. - Greenville DE
International Classification:
C07D30728
US Classification:
549295
Abstract:
A cyclocarbonylation process for making. gamma. -butyrolactones under mild temperature and pressure conditions is disclosed. In the process, an allylic alcohol reacts with carbon monoxide in the presence of a rhodium carbonyl catalyst and an amount of a pyridine promoter effective to enhance the selectivity of the process for making the. gamma. -butyrolactone product. The process provides a way of making. gamma. -butyrolactone from allyl alcohol as the only C4 product.

Process For Making Polyetherester Resins Having High Aromatic Diester

View page
US Patent:
58802258, Mar 9, 1999
Filed:
Jul 15, 1998
Appl. No.:
/116112
Inventors:
Lau S. Yang - Wilimington DE
Gangfeng Cai - Westh Chester PA
Diandre Armstead - Philadelphia PA
Assignee:
Arco Chemical Technology, L.P. - Greenville DE
International Classification:
C08F 2000
US Classification:
525440
Abstract:
A process for making polyetherester resins is disclosed. A glycol ester of an aromatic diacid such as terephthalic acid is reacted with a polyether and a source of a dicarboxylic acid such as maleic anhydride to produce a polyetherester resin, wherein the aromatic diester content may be conveniently adjusted as desired. The process permits the preparation of unsaturated polyetherester resins with relatively high levels of terephthalate repeating units while avoiding the difficulties associated with the direct use of terephthalic acid in previously known procedures. Such unsaturated polyetheresters are useful for making thermoset resins with excellent mechanical and physical properties. New glycol esters based on 2-methyl-1,3-propanediol, and polyester resins and thermosets made from the glycol esters, are also disclosed.
