CITRATE ESTER COMPOSITIONS AND PROCESSES FOR THEIR PREPARATION |
摘要 |
Citrate ester compositions which are useful as compatible components in a resinous system for sheet molding compositions and have general formula (I), wherein X is selected from the group consisting of ( alpha ) and OH are disclosed. Also disclosed is a sheet molding composition which includes a four component resinous system comprising (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 thermoplastic polymer additives which cause phase separation and internal voids during the curing reaction; (c) one or more olefinically unsaturated monomers which copolymerize with the unsaturated polyester; and, (d) one or more compatible components which remain compatible when the polyester and monomer cure and impart improved surface characteristics when added to typical low-profile resin systems. |
