Synthesis and Characteristics of Pentaerythritol Triacrylate

Pentaerythritol triacrylate is a common acrylate monomer and is mainly used in polymer preparation.Pentaerythritol triacrylate is an esterification reaction between pentaerythritol and acrylic acid. Generally, acid is used as a catalyst. The feed ratio and the removal of water are the keys to promote the reaction. In addition, a polymerization inhibitor needs to be added during the reaction.

Pentaerythritol triacrylate is an acrylate obtained by esterifying 1 part of pentaerythritol with three parts of acrylic acid. It has the characteristics of typical acrylates. In addition, there is a side chain hydroxyl group in the molecule. The presence of hydroxyl groups on the one hand enhances the polarity of the molecule and reduces volatility. On the other hand, it can be used as a reaction site to connect to other materials by grafting methods for the preparation of composite materials.
