UV-Curable Acrylated Oligomers: Effect of Structural Variation on Liquid and Cured Film Properties

摘要

Unique acrylate functional oligomers have been developed with the concept of versatile property selection in mind. Spectroscopic structural confirmation using model compounds has demonstrated that synthesis of the desired compositions has been achieved. A variety of oligomeric compositions have been synthesized and characterized. When formulated into typical UV curable coatings, a range of liquid and film properties become attainable depending upon the oligomer being used. Cured films covering the spectrum from soft and flexible to hard and brittle have been made. This study will focus on the range of properties achievable using these oligomers. Selection of a suitable oligomer composition required to attain desired film properties has become apparent. In certain cases, a sufficiently wide range of properties has been found to suggest the use of a single oligomer for multiple applications.
