Patent number: 5780558Abstract: A low-cost way to modulate the reactivity and acid number of polyetherester thermoset resins is disclosed. "Beginning" and "end" methods for making dicyclopentadiene (DCPD)-modified polyetherester resins are described. The "beginning" method comprises first heating a polyether, DCPD, a diol, an insertion catalyst, and a carboxylic acid derivative to produce a mixture that contains the polyether and a DCPD-diol diester adduct.

Compared with DCPD polyester resins, those of the invention give more flexible thermosets. Compared with unmodified polyetherester resins, the DCPD polyetherester resins offer formulators more control over curing, which eliminates mold distortion and shrinking or cracking of thermoset parts.Type: GrantFiled: September 25, 1997Date of Patent: July 14, 1998Assignee: Arco Chemical Technology, L.P.Inventors: Jeffrey A.

The compositions comprise a first component comprising at least one reactive thinner and at least one unsaturated polyester, and a second component comprising a curing catalyst. The unsaturated polyester of the first component is the reaction product of: (a) a mixture of at least one saturated aliphatic dicarboxylic acid with 6 to 10 carbon atoms and at least one ethylenically unsaturated aliphatic dicarboxylic acid selected from maleic acid, fumaric acid, itaconic acid, citraconic acid, and mixtures thereof; (b) a diol component consisting of at least one of 1,4-dimethylolcyclohexane and substituted dimethylolcyclohexanes, with up to 50 mol % monomeric or oligomeric glycol, based on total moles of the diol component; and (c) up to 10 mol % of a polyol, based on total moles of polyester reactants. The compositions and processes of the invention result in coatings with improved hardness and aged cold crack resistance.Type: GrantFiled: August 28, 1995Date of Patent: February 4, 1997Assignee: BASF Lacke + Farben, AGInventors: Karl-Dieter Depping, Horst Hintze-Bruning

Patent number: 5569737Abstract: A process for making polyetheresters is disclosed. A polyether is reacted with a carboxylic acid in the presence of a strong protic acid or a metal salt of a strong protic acid to promote insertion of the carboxylic acid into polyether carbon-oxygen bonds to produce a polyetherester. The polyetheresters are useful for various applications in the polyurethane and unsaturated polyester industries.Type: GrantFiled: April 10, 1995Date of Patent: October 29, 1996Assignee: Arco Chemical Technology, L.P.Inventors: Lau S. Yang, Jeffrey A. Klang

Patent number: 5516819Abstract: A method of producing a thickened organic polymeric composition useful for molding and capable of resisting post-molding shrinkage after being crosslinked comprising a cross-linkable base resin dissolved in an unsaturated monomer, and an additive resin selected from saturated polyesters and saturated amide waxes, the additive resin being crystalline at ambient temperatures and having a melting point (T.sub.m) below a temperature (T.sub.c) at which the base resin cross-linking reaction proceeds at a significant rate. The base resin and additive resin have only a partial degree of compatibility. When cooled from a temperature between T.sub.m and T.sub.c to temperature between T.sub.m and ambient the composition thickens, whereas, when it is heated to a temperature below T.sub.c, it reverts to a flowable composition.Type: GrantFiled: August 25, 1994Date of Patent: May 14, 1996Assignee: The University of Manchester Institute of Science and TechnologyInventors: Stephen F. Bush, James M. Methven, David R. Blackburn

Patent number: 5504126Abstract: The subject invention provides an improved simulated mineral article which comprises a discrete suspended plastic material and a continuous thermoplastic matrix. The plastic material and the thermoplastic matrix are visually distinguishable and each contains a coupling agent. The subject invention also provides a method of preparing a simulated mineral article which entails preparing a liquid thermoplastic to serve as a matrix and then suspending a plastic material therein. The plastic material is composed of a thermoset plastic made from resin which comprises an acid component having thermoplastic characteristics. The invention also concerns a method of coating a thermoplastic article with a thermoset surface coat which has increased binding affinity toward the article.Type: GrantFiled: March 4, 1994Date of Patent: April 2, 1996Assignee: Safas CorporationInventor: Akbar Ghahary
