Synthesis, properties, and hydrolysis of bio-based poly(butylene succinate-co-diethylene glycol succinate) copolyesters was written by Ding, Yue;Li, Shilin;Wang, Jingxi;Liu, Yuanyuan;Dong, Liming;Du, Xihua;Huang, Dan;Ai, Tianhao;Ji, Junhui. And the article was included in Journal of Applied Polymer Science in 2022.Name: 2,2′-Oxybis(ethan-1-ol) This article mentions the following:
A series of poly(butylene succinate-co-diethylene glycol succinate) (PBSD) copolymers were synthesized by melt-polycondensation in order to improve the nonenzymic hydrolysis of PBS. The contact angle and water uptake content of copolymer were increased obviously when the regular crystalline structure of chain segment was disturbed by diethylene glycol. Rheol. tests revealed the microphase separation structure occurred at 130°C. The tensile strength of PBSD40 copolymer was 15 MPa and the elongation at break was more than 700%, and the decomposition temperature was above 370°C. The weight loss of PBSD60 copolymer in acid condition was 98.6% after 49 days at 50°C. However, in neutral condition and simulated seawater, the weight loss was less than 10%. Acid and alk. catalyzed the hydrolysis of ester bonds. Some holes and cracks appeared at the surface of the samples after degradation from SEM anal. Thus, PBSD copolymers have the potential to serve as promising water degradable materials. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Name: 2,2′-Oxybis(ethan-1-ol)).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Name: 2,2′-Oxybis(ethan-1-ol)
