摘要

In this work

trialdehydes

diamines

and trimethylsilyl cyanide could easily undergo multicomponent polymerization under mild conditions

producing hyperbranched poly(α-aminonitrile)s with high molecular weights in good yields. The hyperbranched poly(α-aminonitrile)s show good solubility

high thermal stability and morphological stability. Furthermore

these

-poly(α-aminonitrile)s can undergo post-polymerization with high efficiency.

Abstract

Functional hyperbranched polymers

as an important class of materials

are widely applied in diverse areas. Therefore

the development of simple and efficient reactions to prepare hyperbranched polymers is of great significance. In this work

trialdehydes

diamines

and trimethylsilyl cyanide could easily undergo multicomponent polymerizatio

n under mild conditions

producing hyperbranched poly(

-aminonitrile)s with high molecular weights (

up to 48700) in good yields (up to 85%). The hyperbranched poly(

-aminonitrile)s have good solubility in commonly used organic solvents

high thermal stability as well as morphological stability. Furthermore

due to the numerous aldehyde groups in their branched chains

these

-poly(

-aminonitrile)s can undergo one-pot

two-step

four-component post-polymerization with high efficiency. This work not only confirms the efficiency of our established catalyst-free multicomponent polymerization of aldehydes

amines and trimethylsilyl cyanide

but also provides a versatile and powerful platform for the preparation of functional hyperbranched polymeric materials.
