PROCESS FOR PREPARING DIFFERENTIALIZED PREPOLYMERS WITH CARBOXYLENE GROUPS AND DEFINED MOLECULAR WEIGHT RANGE |
abstract |
The invention relates to a process for the preparation of difunctionalized prepolymers having carboxyl end groups and a defined molecular weight range in which amide-group-containing polymers are degraded in a defined manner. These substances can be used as starting material for block cocondensation to ABA-type polymer. |
