Process for preparing polyamides of PACP

Process for preparing polyamides of PACP

A process for preparing polyamides of 2,2-bis(4-aminocyclohexyl)-propane (PACP) or methyl derivatives thereof with a C8 to C12 straight chain alkane dicarboxylic acid, or mixture thereof with adipic acid, which comprises preparing a moderate molecular weight prepolymer of the diamine and diacid or d...

Zusammenfassung:A process for preparing polyamides of 2,2-bis(4-aminocyclohexyl)-propane (PACP) or methyl derivatives thereof with a C8 to C12 straight chain alkane dicarboxylic acid, or mixture thereof with adipic acid, which comprises preparing a moderate molecular weight prepolymer of the diamine and diacid or diacid mixture employing a manganous hypophosphite/water catalyst system, and thereafter condensing the prepolymer to a high molecular weight product.
