Description
(2)一般式R 1 O−R 2 −NH 2 で表されるアルコキシアルキルアミン化合物が、特に、メトキシエチルアミン、メトキシプロピルアミン、エトキシメチルアミン、エトキシエチルアミンであって、これらから選ばれたアルコキシアルキルアミン化合物を一つ以上使用することを特徴とする請求項1に記載の医療用具の製造方法
このアルカリ処理に用いられるアルカリとしては、上記カルボキシル基をアルカリ塩へ変換する目的を達成できるアルカリであれば使用可能であるが、潤滑耐久性の点から、特に、水酸化ナトリウム、水酸化カリウムの水溶液、アルカリ金属アルコキサイドのアルコール溶液などで処理するのが最も良い結果を与える。
また、アルカリ処理後、水、生理食塩水、エタノールなどで十分洗浄を行い、アルカリを完全に除去することが好ましい。

- 無水マレイン酸共重合化合物と一般式R 1 O−R 2 −NH 2 で表されるアルコキシアルキルアミン化合物(式中R 1 は炭素数が1〜3のアルキル基、R 2 は炭素数が1〜3のアルキレン基)を反応させることによって、前記の共重合無水マレイン酸環の10〜100モル%がアミド結合に変換された無水マレイン酸共重合化合物を、医療用具を構成する基材の表面に塗布し、乾燥した後、さらに、水酸化ナトリウム、水酸化カリウムの水溶液あるいはアルカリ金属アルコキサイドのアルコール溶液などのアルカリで処理することを特徴とする優れた潤滑耐久性、生体適合性を有する医療用具の製造方法
- 一般式R 1 O−R 2 −NH 2 で表されるアルコキシアルキルアミン化合物が、特に、メトキシエチルアミン、メトキシプロピルアミン、エトキシメチルアミン、エトキシエチルアミンであって、これらから選ばれたアルコキシアルキルアミン化合物を一つ以上使用することを特徴とする請求項1に記載の医療用具の製造方法
