Process for producing amine functional derivatives of poly (vinyl alcohol) |
| abstract |
This invention relates to a process for producing an aminoalkylal derivative of polymer containing a plurality of polymerized vinyl alcohol units which are vicinal, preferably a process for producing the 4-aminobutyral of poly(vinyl alcohol). The improved process for the amino-acetalization of such polymers described herein comprises reacting a 5 of 6 member cyclic imine of the structure wherein n is an integer from 3 to 4 with the polymer containing a plurality of polymerized vinyl alcohol units. In a preferred reaction, 1,2-pyrroline is reacted with the polymer containing polymerized vinyl alcohol units under acidic conditions. Preferably the reaction is carried out by a slurry phase process employing a non solvent carrier such as methanol for the poly(vinyl alcohol). The reaction scheme for preparing the 4-aminobutyral of poly(vinyl alcohol) may be characterized by the following equation. |
