摘要： A sheet molding composition is disclosed which includes a four component resinous system which comprises (a) an unsaturated polyester comprising a polycondensation product of one or more dihydric alcohols and one or more ethylenically unsaturated polycarboxylic acids; (b) one or more low-profile additives which are thermoplastic polymers which cause phase separation and porosity during the curing reaction; (c) one or more olefinically unsaturated monomers which copolymerizes with the unsaturated polyester; and, (d) one or more compatible components containing one or more polyoxyethane substituents. The compatible components remain compatible when the polyester and monomer cure and impart improved surface characteristics when added to typical low-profile resin systems.

摘要： A sheet molding composition is provided which exhibits controllable thickening. The composition includes a low molecular weight polyester in which some of the chain ends have been endcapped with functional groups which are unable to react with the thickeners employed in the sheet molding composition. The sheet molding composition has a low viscosity of from about 6 to about 20 million centipoise which allows molding at low pressures of from about 100 to about 300 psi.
