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.

The employment of the modified urethane prepolymer composition provides for the reduction in the amount of styrene monomer used in the unsaturated resin composition and also provides for improved chemical and physical properties of the cured, unsaturated resin composition, such as a reduction in glass roll-out when the resin composition is employed with fiberglass.

Abstract: Apparatus and method for the production of hopper feedable thermoplastic pellets having zones or compartments which contain physically separated reactants which react only after being melt-mixed, as in a screw type extruder, reciproscrew injection machine, or similar device which heat forms pellets into a larger mass. This new class of thermoplastic molding materials relies mainly on the relatively slow reaction kinetics of contained large molecule molding materials to provide a time interval after melt-mixing of zoned pelletized reactants in an extruder barrel or injection molding machine. During this time period, the thermoplastic molding material is easily filled into injection molds. As the reaction progresses, the material becomes more viscous and such flow is difficult or impossible. The involved reactions may continue after demolding at room temperature during a post molding cure, or appliance service generated heat may cause post molding cure.
