    New route for polycarbonates
    (Publishing House of Lviv Polytechnic National University, 2009) Brzozowski, Zbigniew; Stec, Anna; Wielgosz, Zbigniew
    A new route for obtaining chemically pure and ecological polycarbonates has been developed. The process was carried out without any amines with dimethylosulfoxide (DMSO) as interfacial catalyst. It was established that DMSO was between 80–120 mol % to the quantities of applied monomers. Bisphenol A and bisphenol C [2,2-bis(p-hydroxyphenyl),-1,-1 dichloroethylene] were applied as bisphenolic monomers. Розроблено новий напрямок одержання хімічно чистих і екологічно безпечних полікарбонатів. Показано, що процес протікає у відсутності амінів з використанням міжфазного каталізатора диметило-сульфоксиду (ДМС). Встановлено, що концентрація ДМС заходиться в межах 80-120%омол в розрахунку на кількість використаних монометрів. Як бісфенольні мономери застосовано біофенол А і біофенол С [2,2-біс(р-гідроксифеніл) 1,-1дихлороетилен].
