Abstract: 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.

Abstract: Processes for making storage-stable epoxy-capped polyetherester resins are disclosed. In one process, a polyetherester resin is first made by inserting a carboxylic acid derivative into a polyether. Reacting the resin with a capping agent gives an intermediate resin with a reduced content of free carboxylic acid groups. Finally, the intermediate resin reacts with an epoxy compound in the presence of a finishing catalyst under conditions effective to give an epoxy-capped resin. The resins have low weight average molecular weights (less than about 8000), narrow molecular weight distributions (less than 6), and low viscosities, making them an excellent choice for low-VOC formulations. The finishing catalyst helps to minimize resin viscosity drift and improves shelf stability. Curing the resins with a vinyl monomer gives thermosets with an excellent balance of physical properties, including excellent water resistance.
