Kinetic Study on Photopolymerization of TPGDA under Containerless Condition

Abstract:

The TPGDA drop was suspended in the atmosphere under acoustic levitation and induced by photoinitiation for polymer preparation at the first attempt. The kinetics of TPGDA photopolymerization induced by the UV light under containerless condition was studied. Compared to the normal condition, the average initial polymerization rate of TPGDA under acoustic levitation is relatively lower, while the final conversion is higher. Relative to oxygen inhibition, container effect plays a more significant role on the conversion in this polymerization system.
