  • FORMULATIONS COMPRISING ISOSORBIDE-MODIFIED UNSATURATED POLYESTER RESINS AND LOW PROFILE ADDITIVES WHICH PRODUCE LOW SHRINKAGE MATRICES
    Publication number: 20110040004
    Abstract: Formulations comprising an isosorbide-modified unsaturated polyester comprising maleic acid, fumaric acid, itaconic acid or maleic anhydride and isosorbide and one or more low profile additives. The formulations exhibit better shrink control in molding compound formulations with standard low profile additives than their non-isosorbide-modified analogues. These isosorbide-modified unsaturated polyester resins may be applied in molding compounds like sheet molding compounds or bulk molding compounds and may be components of fiber reinforced composites or other composite materials.
