MAQOLA ANNOTATSIYASI

Мuammoning kelib chiqishi. Akril- va metakrilamid hosilalari orasida Ngidroksilguruhсaqlovchi alkilakrilamidlar: tekstil, oziq-ovqat va farmatsevtika sanoatida, qishloq xo’jaligida keng qo’llanilayotgan ionogen sopolimerlar, fiziologik-faol va suvda eruvchan sopolimerlar muhim o’rin tutadi, chunki ular maxsus xossali yangi sopolimerlar olish imkonini beradi. Shu nuqtai nazardan yangi gidroksilguruhсaqlovchi N-metilakrilamid (MAA) bilan N-vinilpirrolidon (VP) va N-vinilkaprolaktam (VKL) sopolimerlar sintezi va tadqiqi qiziqish uyg’otadi. Ishning maqsadi. Monomerlarning sopolimerizatsiya barqarorligini, faolligi va qutbliligini aniqlashdan iborat. Monomer aralashmasini, tarkibini va sintez sharoitini boshqarib berilgan tarkibli mahsulotlarini olish va almashish darajasini aniqlash mumkin. Metilolamid guruhlarning chuqur gomofaza sopolimerizatsiyasi jarayonida monomerlarning nisbiy faolligiga ta'sirini aniqlash. Metodologiya. Dimetilformamidda N-methylolacrylamid bilan N-vinillaktamning radikal sopolimerizatsiyasini tadqiq qilish, initsiator sifatida dinitrilazobisizomoy kislotasidan foydalanib dilatometrik usulda o'rganish. Ubbelode viskometrida xarakteristik qovushqoqligini aniqlash. Element analiz va IQ-spektroskopiyasi yordamida olingan sopolimerlarning tarkibini o'rganish. Ilmiy yangiligi. N-metilolakrilamid bilan N-vinilpirolidon va N-vinylcaprolactam sopolimerlanishining ba'zi xossalarini tadqiqoti va sintezi. Olingan natijalar. Qo’shimcha faollashtirishni talab etmaydigan va turli kimyoviy reaktsiyalarga mahsus sharoitni talab etmasdan kirishadigan, turli funktsional guruhlari bo'lgan yuqori molekulyar birikmalar sintez qilingan. Xususiyatlari: - N-metylolacrylamide bilan N-vinilpirolidon va N-vinylcaprolactam sopolimerlari sintez qilindi; - monomerlarning sopolimerlanish, faollik va qutblilik konstantalari va qovushqoqligi aniqlangan. - olingan sopolimerlarning tarkibi o’rganilgan.
