ABSTRACT:
The disclosure teaches the gelling and thickening of matrix forming resin systems by ion-dipole bonds. Suitable ions are introduced into the resin matrix as alkaline oxides or hydroxides. Thermoplastic polymers containing polar groups are used as additives for the thermosetting resins to offset shrink of the thermosetting resins during their crosslinking and curing in the molding operation. In the molded thermoset state of the resin materials, the polar groups provide sites for the improved bonding of paints, as for example, gel coats. The invention has particular advantages in polyester thermosetting resin systems and in the thermoplastic additives that are used therewith. Polar monomers copolymerized with styrene are the preferred thermoplastic additives.
