Method for production of modified oxymethylene polymers |
| abstract |
Disclosed herein is method for production of modified oxymethylene polymers by a coupling reaction of an oxymethylene polymer and a dissimilar organic polymer with an isocyanate or an isothiocyanate. The method comprises the consecutive steps of (1) forming an admixture of an organic tin catalyst and the reactive components; and then (2) adding an organic phosphite to enhance the reaction rate. When this sequence is followed a synergistic reaction rate is observed. |
