Mazkur maqolada piroliz mahsulotidan ajratib olingan indensulfo birikmasi
asosida formaldegid ishtirokida sintez qilingan polimerning fizik-kimyoviy xossalari, xususan,
gravimetrik usul orqali bo‘kish parametrlari o‘rganildi. Polimerning suvda bo‘kishi sentrifugalash
va vakuumli filtrlash usullari orqali baholandi hamda harorat va vaqtga bog‘liq bo‘lishi aniqlandi.
Tajriba davomida bo‘kish koeffitsienti, fazoviy to‘rning molekulyar massasi (Mc), zichlik va
hajmiy ulush (φ) kabi asosiy ko‘rsatkichlar hisoblab chiqildi. Shuningdek, polimer zanjiridagi
guruhlar soni va tarmoqlanish darajasi aniqlanib, 6 ta monomer birligidan so‘ng tarmoqlanish
yuzaga kelishi ko‘rsatildi. Ushbu ish natijalari polimetilenindensulfokationitning strukturaviy
xususiyatlarini chuqurroq tushunishga yordam beradi hamda kelgusidagi amaliy tadqiqotlar uchun
ilmiy asos bo‘lib xizmat qiladi.
