Facile synthesis and applications of polypropylene/polydimethylsiloxane graft copolymer

It is of great significance to synthesize polyolefin/polysiloxane hybrid materials due to their unique combination of crystalline polyolefin segments and semiorganic polysiloxane segments. Herein, we report the syntheses of a novel polypropylene/polydimethylsiloxane (PP‐g‐PDMS) graft copolymer via t...

Description
Summary:It is of great significance to synthesize polyolefin/polysiloxane hybrid materials due to their unique combination of crystalline polyolefin segments and semiorganic polysiloxane segments. Herein, we report the syntheses of a novel polypropylene/polydimethylsiloxane (PP‐g‐PDMS) graft copolymer via the coupling reactions between maleic anhydride‐grafted PP and monoaminopropyl‐terminated PDMS. The chemical structures of PP‐g‐PDMS have been characterized by Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR), and gel permeation chromatography (GPC). The correlation between reaction conditions and the structural parameters of PP‐g‐PDMS has been established. Consequently, the potential applications of resultant PP‐g‐PDMS were investigated, and the results showed that PP‐g‐PDMS can serve as an efficient compatibilizer in heterogeneous PP/PDMS blend system and also as an ideal processing aid for high‐viscosity PP.
