DMTA Analysis of Glycerol Diglycidyl Ether Based Photocross-linked Polymers

Abstract

In this paper, the effect of the amount and chemical structure of the structurally different alcohols on the rheological properties of the photocross-linked glycerol diglycidyl ether based polymers was investigated by dynamic-mechanical thermal analysis. The glass transition temperatures of photocross-linked polymers were determined from the onset point of storage modulus G' curve, maximum peak of loss modulus G'' curve and the maximum peak of the loss factor tanδ curve. The lower concentration of alcohol was used in the batch the higher glass transition temperature and the increased height of the storage modulus G' curve was obtained as a consequence of the formed more rigid structure of polymers.
