Abstract
Description
(上記式中の官能基数とは、カーボネート化合物とアミン化合物がそれぞれの1分子中に有する環状カーボネート構造またはアミノ基の個数である。)
前記5員環環状カーボネート基を反応性基として有する化合物が、二酸化炭素を原材料の一つとして合成されたものであり、該化合物を反応に用いて得たポリマー中に、上記二酸化炭素由来の-O-CO-結合が1~30質量%含有されていること。より好ましくは、ポリマー微粒子の質量のうち1~40質量%が二酸化炭素由来の-O-CO-結合から構成されたものとなること;
前記分散剤として、その構造中に非極性部と極性部とを有し、該非極性部はポリブタジエン骨格を有し、かつ、該極性部は、5員環環状カーボネート構造もしくはヒドロキシウレタン構造のいずれかを有するものを用いること;
さらに、前記不活性液体中に分散している状態のポリマー微粒子から該不活性液体を取り除き、粉末状のポリマー微粒子にして取り出すことである。
本発明のポリヒドロキシウレタン微粒子は、粒子径が0.1μm~300μmである球状のポリマー微粒子であって、該微粒子を構成するポリマーが、その構造中に、下記(1)又は(2)で表される化学構造ユニットの少なくともいずれか一方を有し、これらの化学構造ユニットを構成している-O-CO-結合が二酸化炭素由来であることを特徴とする。
本発明のポリヒドロキシウレタン微粒子は、上記式(A)で示される反応を利用することで得ることができる。具体的な製造方法では、少なくとも2つの5員環環状カーボネート基を反応性基として有する化合物(以下、単に環状カーボネート化合物と略す場合がある)と、少なくとも2つのアミノ基を反応性基として有する化合物(以下、アミン化合物と略す場合がある)とを必須成分として用い、これらの化合物を、分散剤を含む不活性液体中に均一に分散させた後、加熱して両化合物を反応させることで、不活性液体中に分散した状態のポリヒドロキシウレタン微粒子を得る。さらに、本発明の製造方法では、上記で必須とする2種の化合物のどちらか一方に、1分子中に3つ以上の反応性基を有する化合物を用い、かつ、両化合物を官能基当量比0.7~1.5で反応させる。
以下において、それぞれの反応に使用した環状カーボネート化合物とアミン化合物との「官能基当量比」は、下記式を用い、下記のようにして算出した値である。
上記の算出式で必要となる環状カーボネート化合物の「官能基数÷カーボネート化合物の分子量」は、カーボネート化合物1gあたりのカーボネート基のモル当量を示す指数であることから、これを「カーボネート当量」と定義し、以下の測定方法により実測した。このようにした理由は、実施例で使用したエポキシ化合物と二酸化炭素から合成した環状カーボネート化合物は、1分子中におけるカーボネート基の数が異なるものの混合物として得られるためである。なお、アミン化合物についてはこの問題はなく、分子量からモル当量を求めることができる。
また、各実施例で使用したカーボネート基中の-O-CO-結合は、二酸化炭素に由来するものであることより、上記で得た「カーボネート当量」から、カーボネート化合物中の二酸化炭素含有量を算出できる。すなわち、二酸化炭素含有量(%)は、[カーボネート当量(eq/g)×44(=CO2分子量)×100]で求めることができる。本発明では、二酸化炭素含有量は上記のようにして計算で求めた。
