本文研究了在乙醇溶剂中用过氧化氢引发聚合的端羟基液体聚丁二烯(简称丁羟)的~(13)C-NMR谱,发现了RCH=CHCH_2OH(反式)和RR′C=CHCH_2OH共振峰,肯定了这两种端基结构。确定了在聚合过程中乙醇转移到分子链端的主要结构是RCH=CHCH_2CH(OH)CH_3(顺式和反式),它占羟基总量8％左右。工作还确认,在丁羟中尚存在少量的长支化结构以及醇、醛端基结构。 In this paper, ~ (13) C-NMR spectra of terminal hydroxyl-terminated liquid polybutadiene initiated by hydrogen peroxide in ethanol solvent were studied and found that RCH = CHCH_2OH (trans) and RR’C = CHCH_2OH resonance peak, affirmed the two terminal structure. It was confirmed that the main structure of ethanol transfer to the molecular chain end during polymerization was RCH = CHCH 2 CH (OH) CH 3 (cis and trans), accounting for about 8% of the total amount of hydroxyl groups. The work also confirmed that there is still a small amount of long-branched structure in the hydroxyl and alcohol, aldehyde terminal structure.
