Amine-containing graft polymers, a method for making same, and their use

摘要

Graft polymers containing primary amine functionality are prepared by reacting a thermoplastic polymer containing at least one electrophilic functionality sufficient to react with primary amine groups with a chemical compound having one primary amine group and at least one protected primary amine group. By utilization of the selected protecting groups, crosslink formation is essentially avoided. After grafting of the amine-containing compound, the protecting groups are removed and replaced with hydrogen atoms to restore primary amine functionality in the pendant amine group. By utilization of the selected deprotection processes, the chemical bonds in the amine compound and those binding the amine to the polymer are substantially unaffected.
