The analysis of the polymer degradation mechanism by a micro ultraviolet-irradiation system

Abstract

The analysis which mainly used the degradation residual for the deterioration-mechanism analysis of the polymer is in use. However, many volatilizing components are also contained in the degradation reaction of a polymer, and just an analysis of a residual may be insufficient for clarifying a reaction mechanism completely. AC-2235 analyzed the deterioration mechanism using the micro ultraviolet-irradiation system. AC-2235 is a copolymer of PMMA and PBA. From the result of μ-UV/Py-GC/MS, AC-2235 made it the evident to decompose both component of PMMA and PBA by the UV rays.
