And the article contained the following:
In this study, a novel bisphenol-containing cyclohexane group [4,4′-(cyclohexane-1,1-diyl)bis(2-methoxyphenol) (CDBMP)] was synthesized. It was reacted with 4,4′-dichlorodiphenylsulfone to synthesize polyether sulfone-containing -OCH3 groups (PES-OCH3). Then, PES-OCH3 was reacted with BBr3 and (t-Boc)2O to yield PES-OH and PES-Boc, resp. The glass transition temperatures of PES-OCH3 and PES-OH were found to be 177.6 and 240.7°C, resp. The resultant resins exhibited good tensile strength and solubility (dissolved in N-Methyl-2-Pyrrolidine, DMF, and so on). Interestingly, PES-Boc showed excellent foam property, and the d. of the foam decreased from 1.23 to 0.012 g/cm3. Also, we found that the dielec. constant and dielec. loss values (107 Hz) of the foaming sample were in the range of 1.9-2.7 and 4.22 x 10-3 to 7.99 x 10-3, resp. The introduction of hydroxyl-Boc-assisted modification provides a controllable process to fabricate porous and ultra-light materials, and it can be potentially applied in these fields such as microelectronics and high speed communication systems. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Related Products of 80-07-9
