Abstract
Polyester-polyurethane hybrid resin molding compositions having low levels of unsaturation which are modified by the addition of a low profile additive to provide glass-reinforced articles that have improved surface profiles and improved processability compared to commercial low profile-modified unsaturated (non-hybrid) polyester resins.
