    Synthesis of peroxy oligomers using 1,2-epoxy-3-tertbutyl peroxypropane
    (Publishing House of Lviv Polytechnic National University, 2008) Bratychak, Michael; Bratychak, Mikhailo; Astakhova, Olena; Shyshchak, Olena
    The possibility of peroxy oligomer synthesis has been studied by three methods: telomerization of diepoxy derivatives of ethylene glycol or Bisphenol Ausing 1,2-epoxy-3-tert-butyl peroxypropane as telogen, modification of phenol-formaldehyde resins by 1,2-epoxy- 3-tert-butyl peroxypropane and polycondensation of phenol containing –O–O– bonds with formaldehyde. The peroxy oligomers obtaining conditions have been established and 7 new oligomers with peroxy groups have been synthesized. The structures of synthesized oligomers have been verified by chemical and spectral methods. Вивчена можливість синтезу пероксидних олігомерів трьома методами: теломеризацією діепоксидних похідних етиленгліколю або біофенолу А з використанням 1,2-епокси-3-трет-бутил пероксипропану як телогену, модефікацією фенол-формальдегідникомол 1,2-епокси-3-трет-бутил пероксипропаном поліконденсацією фенолу, що містить -О-О- зв'язки, з формальдегідом. Встановлено оптимальні умови одержання пероксидних олігомерів та синтезовано 7 нових олігомерів. Структуру синтезованих олігомерів підтверджено хімічними та спектральними методами досліджень.
