Usmanov, S. M.; Berlin, A. A.; Kochervinskii, V. V.; Sivergin, Yu. M.; Shashkova, V. T.; Zelenev, Yu. V. published an article in 1976, the title of the article was Dielectric relaxation in oligoester acrylates.Name: 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate) And the article contains the following content:
The dielec. relaxation behavior for 4 oligoester acrylates (OEA) showed that glassification in the OEA was of a cooperative nature and could be described by the Onsager model. The OEA studied were α,ω-bis(methacryloyloxy)-2,2-dimethylpropylene [1985-51-9] and the α,ω-bis(methacryloyloxyethyleneoxycarbonyloxy) derivatives of propylene [60028-80-0], 2,2-dimethylpropylene [54547-48-7], and 2,2-dichloropropylene [61550-96-7]. The relaxation time spectra of the OEA reflected contributions by different forms of high-frequency intramol. motion during the α relaxation process and by the cooperative occurrence of glassification via strong intermol. interaction. The cooperative nature of the α relaxation mechanism was also indicated by low activation energy values. Calculations using the Frelikh (1960) theory for the B-T dependence at temperatures above the glass temperature indicated a nonordered orientation of dipoles. The experimental process involved the reaction of 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)(cas: 1985-51-9).Name: 2,2-Dimethylpropane-1,3-diyl bis(2-methylacrylate)
