Abstract
A phenolic derivative 2,5&benz has been synthesized from 2,5-dimethylphenol and benzaldehyde in good yield. 2,5&benz showed high crystallinity. In free radical polymerizations new vinyl monomers (ACv-1 and ALBv-1) obtained from 2,5&benz are used to prepare cross-linked polymeric materials by using photo- or thermal initiator. The resulting materials are expected to improve thermal stability, since they have a lot of aromatic rings in polymer chains. DSC and TGA are used to study on thermal properties of the materials. The cross-linked polymeric materials obtained from ACv-1 showed higher thermal stability than that of poly(methyl acrylate). The phenolic skeleton in ACv-1 unit was found to give high thermal stability.
