The effect of nine acrylate-based low profile additives (LPA) with different chemical structure and molecular weight on the volume shrinkage characteristic and internal pigmentability and mechanical properties for the low-shrink unsaturated polyester resin (UP) after the cure were investigated .The experimental results have been explained by phase characteristics of the ternary styrene/UP/LPA system , cured sample morphology , and the volume fraction of microvoid formation during the cure .
