Molecular design of the polymer forming the complex with metal [I]: design of the hard-segments of thermoplastic elastomers by using model compounds
摘要:
The six model hard-segments of thermoplastic elastomers containing a pyridine ring were synthesised and the complexation studied with several metal chlorides. It is found that the model compounds containing MPY group (N-pyrid-2-ylmethyl amide) form the stoichiometric 1:1 complex with ZnCl2 by means of IR. This stoichiometric complexation is caused by the effective formation of the chelate ring between MPY group and ZnCl2. In addition, the complex structure exhibits strong interaction with each other, so that the melting temperature and enthalpy are remarkably increased. As the result, the MPY-ZnCl2 complex structure is the most suitable structure as the hard-segment of thermoplastic elastomers. (C) 1999 Elsevier Science B.V. All rights reserved.
