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. Increasing the temperature causes insertion of the DCPD-diol diester into the polyether to give a DCPD polyetherester resin. The "end" method reacts a polyetherester resin made by insertion with DCPD to give a DCPD polyetherester resin. 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 composition is heated to about 150.degree. to about 170.degree. C., and then to about 200.degree. to about 210.degree. C., which condenses out water, forms an unsaturated polyester and, reduces the acid number to less than about 45. The composition is cooled to a temperature below about 150.degree. C., and about 0.1 to about 0.5% of an inhibitor is added to said composition, followed by an unsaturated aromatic compound which can be styrene, vinyl toluene, or mixtures thereof, in a ratio of about 20 to about 40 pbw unsaturated aromatic compound to about 60 to about 80 pbw unsaturated polyester. When it is desirable to use the composition, 0.5 to about 1.Type: GrantFiled: January 9, 1987Date of Patent: June 21, 1988Assignee: Westinghouse Electric Corp.Inventor: Daniel R. Sassano

Patent number: 4690956Abstract: Graft polymer dispersions in polyoxyalkylene polyether polyols are employed together with flame retardant compounds to prepare flame retardant polyurethane foams. The polymer dispersions employ less than 0.1 mole of induced unsaturation per mole of polyol mixture. Processes for the preparation of these polymer dispersions employ fumarate derived polyetherester polyols or polyetherester polyols prepared by reacting a polyoxyalkylene polyether polyol with a compound selected from the group consisting of maleic acid, maleic anhydride and fumaric acid and an alkylene oxide in the presence of salts and oxides of divalent metals. The polymer dispersions are prepared in the presence of a reaction moderator and employ 50 weight percent or more of acrylonitrile.Type: GrantFiled: October 28, 1985Date of Patent: September 1, 1987Assignee: BASF CorporationInventors: Gerhard G. Ramlow, Duane A. Heyman, Oscar M. Grace

Patent number: 4689354Abstract: White graft polymer dispersions in polyoxyalkylene polyether polyols are employed together with flame retardant compounds to prepare flame retardant polyurethane foams. The polymer dispersions employ less than 0.1 mole of induced unsaturation per mole of polyol mixture. Improved processes for the preparation of these polymer dispersions employ either maleate or fumarate derived polyetherester polyols or polyetherester polyols prepared by reacting a polyoxyalkylene polyether polyol in the presence of a chain transfer agent with a compound selected from the group consisting of maleic acid, maleic anhydride and fumaric acid and an alkyklene oxide in the presence of salts and oxides of divalent metals.Type: GrantFiled: October 23, 1985Date of Patent: August 25, 1987Assignee: BASF CorporationInventors: Gerhard G.
