SINTEZ I STRUKTURNYY ANALIZ STABIL'NYH KARBAMIDOFORMAL'DEGIDNYH OLIGOMEROV C NIZKIM SODERZHANIEM FORMAL'DEGIDA
Abstract and keywords
Abstract (English):
Urea formaldehyde oligomers derivatized from preproduct (got out of 55% formaline and urea formaldehyde concentrate) with no remnant formaldehyde are synthesized. Comparative exercises of synthesized urea formaldehyde oligomers structure are performed using NMR 13С and 1H spectroscopy. Details of full conversion of formaldehyde in oligomer are obtained. Free formaldehyde is exposed in methylene glycol and oligomeric methylene glycol forms only. \
