  • Branched low profile additives and methods of production
    Patent number: 9868814
    Abstract: The invention pertains to low profile additives (“LPA”) comprising branched polymers having a weight average molecular weight (Mw) of at least about 20,000 grams/mole and a number average molecular weight (Mn) of at least about 3,000 grams/mole and methods for making the LPAs. The invention further concerns compositions comprising LPAs synthesized from one or more difunctional monomers and one or more branching agents. Also, disclosed are thermosettable resinous compositions and molded articles comprising the LPAs.
    Type: Grant

  • Formulations comprising isosorbide-modified unsaturated polyester resins and low profile additives which produce low shrinkage matrices
    Patent number: 9034982
    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.
