摘要
The synthesis and characterization of a series of high molecular weight iptycene-containing polymers were presented. Several high molecular weight iptycene-containing polymers were synthesized through a thermally induced radical polymerization of butadiene monomers. Because of their iptycene-based superstructure, these polymers present internal free volume that could be utilized for the enhancement of miscibility and reduction of phase separation in polymer blends. The results show that these polymers with high degrees of free volume can be used in applications benefiting from low densities such as high-performance dielectric materials for semiconductor devices.
