METHOD FOR INHIBITING POLYMERIZATION OF POLYESTER INTO HIGHER MOLECULAR WEIGHT
To inhibit a polycondensation product of a ricinoleic acid containing a prescribed metal component and a derivative, etc. from gradually increasing a molecular weight even at a low temperature, so as to prevent a potential problem in such a polymer in view of morphological stability, moldability, et...

| description | To inhibit a polycondensation product of a ricinoleic acid containing a prescribed metal component and a derivative, etc. from gradually increasing a molecular weight even at a low temperature, so as to prevent a potential problem in such a polymer in view of morphological stability, moldability, etc.SOLUTION: A polyester polymerizing a material containing one kind of a ricinoleic acid containing a prescribed metal component and a derivative thereof, hindered phenol and a prescribed secondary amine compound are simultaneously used to obtain a polyester composition with a stable molecular weight in a low temperature such as a room temperature.SELECTED DRAWING: None
【課題】特定の金属成分を含むリシノール酸およびその誘導体等の重縮合体が、低温においても徐々に分子量が増大すると言う問題点があることが新たに判明した。この重合体は、形状安定性、成形性などの観点で、問題がある可能性が有る。【解決手段】特定の金属成分を含むリシノール酸およびその誘導体の１種を含む原料を重合するポリエステルと、ヒンダードフェノール、特定の２級アミン化合物とを併用することによって、室温の様な低温下において、分子量が安定するポリエステル組成物を得た。【選択図】なし |
