Synthesis and Properties of a Novel Crosslinkable Poly(aryl ether ketone) Containing Naphthalene Group on a Side Chain
摘要
Abstract
A novel crosslinkable poly ( arylene ether ketone) s ( PAEK) with naphthalene pendant was prepared from carboxyl-containing PAEK precursor and naphthalenol by graft reaction. The structures of the polymer before and after grafted were confirmed by FTIR and 1 H NMR spectroscopy. These polymers exhibited good solubility in common organic solvents, such as dimethyl sulfoxide ( DMSO) , N, N-dimethylacetamide (DMAc) , tetrahydrofuran( THF) and chloroform, and could be casted into flexible and transparent films. However, after thermally cross-linked at 170 ℃ for 2 h at air atmosphere, the resulting cross-linked polymer exhibited good chemical resistance, insoluble in above organic solvents. In addition, the cross-linked polymers displayed high thermal stability. The glass transition temperature ( Tg ) and thermal weight loss temperature were obviously increased respectively.关键词
