ABSTRACT:
Methods for preparing reinforced molding compounds are disclosed, comprising preparing a first paste component from a mixture of a thermosetting unsaturated polyester component, a free radical polymerizable monomer component and an inorganic particulate filler component, preparing a second paste component from a conjugated diene butyl elastomer copolymer component, a free radical polymerizable monomer component, and an inorganic particulate filler component, and combining the first and second paste components in order to produce an elastomer modified thermosetting unsaturated polyester molding compound having improved surface appearance, toughness and impact strength. Preferably, one or both of the paste components will include a thermoplastic polymer additive component to provide low profile qualities to the product.
