Abstract: The photopolymerization has developed rapidly for decades, which is efficient, enabling, economical, energy saving, and environmental friendly. However, volume shrinkag occurring in the polymerization is a major drawback for current applications. The causes and consequences of shrinkage have been introduced briefly. The method of reducing polymerization shrinkage was reviewed.
