Title
(JA) 架橋性ポリ(オキシアルキレン)含有ポリアミドプレポリマー
Abstract
(JA)

本発明は、水溶性架橋性ポリ(オキシアルキレン)含有プレポリマーを提供する。本発明の架橋性ポリ(オキシアルキレン)含有共重合体プレポリマーは、アミンでキャップしたポリ(オキシアルキレン)含有ポリアミドを、少なくとも1個のエチレン性不飽和基と、アミンでキャップしたポリ(オキシアルキレン)含有ポリアミドのキャップするアミン基と共反応する官能基と、を有する多官能価化合物と反応させることで製造される。アミンでキャップしたポリ(オキシアルキレン)含有ポリアミドは、(a)少なくとも1種のポリ(オキシアルキレン)ジアミンと、(b)場合により、少なくとも1種の有機ジ−またはポリ−アミンと、(c)少なくとも1種のジカルボキシル誘導体と、(d)場合により、少なくとも1種のポリカルボキシル誘導体と、および(e)カルボジイミドと、を含む混合物の共重合生成物である。本発明の架橋性ポリ(オキシアルキレン)含有プレポリマーは、改善された熱安定性を有するコンタクトレンズを経済的に製造することにおいて使用を見出すことができる。更に、本発明は、医療装置、好ましくは眼科用装置、より好ましくはコンタクトレンズを製造する方法を提供する。
