Özet

© 2022, The Polymer Society, Taipei.In this study, a novel thermosensitive polymer poly(styrene co acrylonitrile co methacrylic acid co n-butylacrylate co diviniyl benzene)(SAMB) is synthesized by solvent polymerization and by copolymerization of styrene, acrylonitrile, methacrylic acid, n-butyl acrylate as a monomer, divinyl benzene as crosslinking agent and benzoyl peroxide as a initiator and poly(styrene co acryl amidoxime co methacrylic acid co n-butyl acrylate co divinyl benzene)(SAMB-Aox) is synthesized by amidoxymation of hydroxilamine hydrochloride, NH2OH·HCl. Firstly, the structure of SAMB and SAMB-Aox is characterized by FTIR, morphology of these polymers is determined by SEM and XRD, thermal properties of SAMB and SAMB-Aox also is specified by DSC and DMA and finally shape memory properties of these polymers were analyzed by bending test SAMB in 45 ℃ and SAMB-Aox at 75 ℃. The shape memory property of SAMB has a Rf value of 76% in 9 s, while the Rf value of SAMB-Aox was measured as 33.3% in 42 s. It was observed that shape recovery value decreased due to the effect of interchain hydrogen bonds after amidoxymation of the polymer.
