Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 78-50-2, is researched, SMILESS is CCCCCCCCP(CCCCCCCC)(CCCCCCCC)=O, Molecular C24H51OPJournal, Article, Analytica Chimica Acta called In situ monitoring of photo-crosslinking reaction of water-soluble bifunctional macromers using magnetic levitation, Author is Ashkarran, Ali Akbar; Sharifi, Shahriar; Abrahamsson, Christoffer K.; Mahmoudi, Morteza, the main research direction is photocrosslinking bifunctional macromer polyethylene glycol diacrylate density magnetic levitation.SDS of cas: 78-50-2.
Crosslinking is one of the fundamental phenomena in polymer science, which happens by forming covalent bonds or relatively short sequences of chem. bonds to join 2 polymer chains. Crosslinking and the subsequent volume shrinkage of monomers/macromers result in changes in their corresponding d. which can be measured using d.-based measurement techniques (e.g., dilatometry). Here, the authors demonstrate a method that allows in situ monitoring of photopolymerization of H2O-soluble bifunctional macromers using magnetic levitation (MagLev) system. The authors use a hydrophobic paramagnetic solution to monitor the photopolymerization of H2O-soluble polyethylene glycol diacrylate (PEGDA) as a model of bifunctional macromers using a ring MagLev system. Based on changes in levitation heights (densities) after illumination of blue light, the authors have successfully monitored the double bond conversion of PEGDA 700 macromers at various polymerization conditions. Probably MagLev can should be used as a new and complementary anal. technique for rapid screening of the photopolymerization reactions and measurement of conversions using changes in the levitation height of the macromers.
