Development of Branched Polymers by Ultrasound-Assisted Melt Mixing Process with Divinyl Terminated Polydimethylsiloxane |
| 초록 |
The chain structure of polymeric molecules is an important characteristic of polymers. Ultrasound-induced polymer scission is a useful route which can either be used as a post-processing step or can be used during ultrasound-induced polymerization. We intended to apply the transformation of molecular structure from linear to branched one during melt processing of polymers. We are introducing a new and reactively simple method by imposing ultrasound and Divinyl Terminated Polydimethylsiloxane(MFA) to produce branched structure. After the ultrasonic irradiation of polymer chains together with MFA, increase in complex viscosities and shear-thinning behavior were observed. The Cole-Cole plot and measurement of extensional viscosities revealed the characteristic features of branched structure with well-defined extensional behavior. It was expected that we may be able to provide information associated with the development of a viable process of polymer modification. |
