金属系ルイス酸触媒は、一般式M(R5)1(R6)1(R7)1(R8)aを有し、ここでaは0または1であり、Mはホウ素、アルミニウム、インジウム、ビスマスまたはエルビウムであり、R5およびR6はそれぞれ独立に、フッ素置換のフェニルまたはメチル基を含み、R7はフッ素置換のフェニルもしくはメチル基または官能基もしくは官能性ポリマー基を含み、任意のR8は官能基または官能性ポリマー基である。フッ素置換のフェニル基とは、少なくとも1個の水素原子がフッ素原子で置換されたフェニル基を意味する。フッ素置換のメチル基とは、少なくとも1個の水素原子がフッ素原子で置換されたメチル基を意味する。R5、R6およびR7は、フッ素置換のフェニル基を含んでよく、またはフッ素置換のフェニル基から実質的になっていてもよい。R5、R6およびR7は、フッ素置換のメチル基、例えば、酸化硫黄(例えば、スルホキシド、スルホニル、スルホン等)と結合したフッ素置換のメチル基の形態を含むことができる。一般式中のMは、金属塩イオンとして存在してもよいし、式の一体的に結合された部分として存在してもよい。
OH価は、=33×%OHとして計算でき、%OH=1700/ポリオールのヒドロキシル当量である。
