Research Abstract

Free radical bulk polymerization of methyl methacrylate(MMA) was carried out in the presence of a macrocyclic amine based on cyclic polystyrene. The polymer changed to an insoluble solid upon heating at 180 ℃ in a vacuum. The insolubility is attributed to the in-situ formation of polypseudorotaxane, followed by the covalent fixation of the threaded ring segment with the linear chain to form noncovalent three-dimensional structure. We have demonstrated a novel synthetic pathway for noncovalent network of PMMA. The synthetic procedure involves in-situ formation of a polypseudorotaxane by free radical polymerization of MMA in the presence of a macrocyclic amine. Evidence for a polypseudorotaxane formation is indicated by GPC, ^1H NMR ; and photoluminescence measurements. Although the amount of the threaded macrocycles. (threading efficiency) remains obscure at this stage, it appears that the large size of macrocyclic amine based on cyclic polystyrene(ca. 60 atoms on average) is favorable for threading. By utilizing the solid-state thermal amidation reaction of the polypseudorotaxane, the covalent fixation of the threaded ring with linear chain results in noncovalent cross-linking to form three-dimensional network
