Measurement of Crystallinity of Acrylic Copolymer by Swelling Differen- tial Scanning Calorimetry

摘要

In this paper the measurement or crystallinity (C) of acrylic copolymer (PAC), by Swelling Dlfferentiai Scan- ning Calorimetry (SDSC) is discussed. Common DSC is only used for measuring the crystallinity of polymers with melting point (T_m ), below their decomposition temper- ature, (T_d ). As temperature rises, polymers with swell- ing agent added become swollen and dissolved, going through Ne process or breaking solid structures.
