Study of phase separation behavior of poly(N,N-diethylacrylamide) in aqueous solution prepared by RAFT polymerization was written by Wu, Mei;Zhang, Haibing;Liu, Hongliang. And the article was included in Polymer Bulletin (Heidelberg, Germany) in 2019.Related Products of 27249-90-7 This article mentions the following:
A series of poly(N,N-diethylacrylamide) samples with low mol. weights (1.9 鑴?103-5.3 鑴?104) and narrow polydispersities (below 1.5 and usually lower than 1.25) was synthesized by reversible addition-fragmentation chain transfer polymerization The phase separation behavior of poly(N,N-diethylacrylamide) in aqueous solution was investigated by turbidimetry, fluorescent probe technol. and DSC. It is interesting to find that the lower critical solution temperature (LCST) of the samples increases with increasing mol. weight and remains more or less a constant above a critical mol. weight of 1.2 鑴?104. At the same time, an inverse dependence of LCST on the concentration was found and this effect was more pronounced for lower mol. weight To further investigate the novel mol. weight dependence of the LCST, the fluorescent probe study was conducted and the exptl. results demonstrated that there was an increase in hydrophobicity when decreasing the mol. weight and increasing the concentration and flower-like micelles were probably formed which can further be proved by TEM. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7Related Products of 27249-90-7).
Benzyl benzodithioate (cas: 27249-90-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Related Products of 27249-90-7
