Abstract
CF 3 SO 3 H was found to serve as a more superior initiator for the polymerization of diisopropenylbenzenes than the conventionally used acids such as H 2 SO 4 . Much faster polymerization at lower temperatures seems to be ascribed to the higher acidity of CF 3 SO 3 H. The use of microflow systems was also found to be effective in increasing the indane unit content, especially for 1,4-DPB. Fast mixing and uniformity of the temperature seem to be responsible. The thus-obtained polymers of high indane unit content serve as useful materials having high thermal resistance and low dielectric constants.
