US Patent:

6342615, Jan 29, 2002

Filed:

May 8, 2000

Appl. No.:

09/566314

Inventors:

Richard William Ryan - Kingwood TX
Ralph Martin Kowalik - Kingwood TX
Michael J. Keenan - Baton Rouge LA

Assignee:

ExxonMobil Chemicals Patents Inc. - Houston TX

International Classification:

C07D30132

US Classification:

549541, 549557, 5253273, 526273

Abstract:

The invention provides for a purified glycidyl ester product prepared from neo acids wherein said ester product is recovered as a light fraction from a glycidyl ester reaction product composition that has been subjected to conditions of temperature and vacuum in a thin film, short pass distillation evaporator, said purified glycidyl ester product further characterized that its polymerizable reaction product with methacrylic acid has a higher effective glass transition temperature as compared with the polymerizable reaction product with methacrylic acid of said glycidyl ester reaction product composition prior to purification.

Filed:

May 21, 1997

Appl. No.:

8/861408

Inventors:

Richard William Ryan - Kingwood TX
Gerald G. McGlamery - Baton Rouge LA
Ralph Martin Kowalik - Kingwood TX

Assignee:

Exxon Chemical Patents Inc. - Houston TX

International Classification:

C07D30132
C07D30316

US Classification:

549541

Abstract:

A process for the distillation of the glycidyl ester reaction product of a straight or branched chain saturated monocarboxylic acid or salt thereof and an halo-substituted monoepoxidc is disclosed, wherein the reaction product is subjected to conditions of temperature and vacuum in a thin film, short pass distillation apparatus such as a wiped film evaporator. The product distillate has significantly reduced color than the reaction product prior to distillation, and has improved heat and color stability.

International Classification:

C08F 2000
C08G 6316

US Classification:

525441

Abstract:

Polyesterdiols having low viscosities of less than 3500 cps, high content of non-volatile matter in excess of 96 wt %, and narrow molecular weight distribution of less than about 1. 4 are prepared by esterification of one or more aliphatic dicarboxylic acids or ester derivatives thereof using at least a 1. 5 molar excess of one or more aliphatic diols until an acid number of less than 20 is achieved, and stripping excess diol from the polyesterdiol reaction product. Where esterification catalyst is used, catalyst is substantially removed prior to stripping excess unreacted diol from polyesterdiol reaction product. The polyesterdiols so produced are useful as (i) curable components in thermosettable resin compositions, particularly compositions essentially free of volatile organic solvent and also containing a crosslinking agent and a reactive hardening agent: and/or (ii) useful as coatings, paints and adhesives, providing coatings with very low content of volatile organic compounds.

Appl. No.:

7/698918

Inventors:

Richard J. Ryan - Marietta GA

Assignee:

United Plastic Films, Inc. - Atlanta GA

International Classification:

B65D 134

US Classification:

220 423

Abstract:

A container for spooled materials comprising: an upper half having at least one generally flat, corrugated rest, an upper flange and a label display surface having a rounded upper portion and a substantially flat, substantially vertical, lower portion; a lower half having a generally flat, corrugated base, at least one end flange and a base-widening lower flange having a base-widening edge extending along the length of the lower half substantially parallel to the base; a hinge joining the upper half with the lower half; and a means for maintaining the upper flange in contact with the end flange so as to define a cavity within the container comprising at least one indentation in the upper flange that nests within at least one indentation in the end flange.
