  From Terphenyl-Dendronized Macromonomers to Aromatic−Aliphatic Polyethers Bearing Two Pendant Dendrons per Repeating Unit

  摘要：

  Novel side chain dendritic aromatic-aliphatic polyethers are synthesized from aromatic terphenyl diols, disubstituted with Frechet-type dendrons of the first and second generation and aliphatic dibromides of various lengths, High-molecular-weight soluble polymers were obtained in all cases. The bulk properties of the polymers were examined by means of thermal analyses (DSC), dynamic mechanical analyses (DMA), and X-ray diffractometry. Separation between the main chain and the dendritic side chains was evident due to the existence of two well-resolved glass transition temperatures, observed by both DSC and DMA measurements.
