Versatile and Controlled Synthesis of Star and Branched Macromolecules by Dendritic Initiation was written by Trollsas, M.;Hedrick, J. L.;Mecerreyes, D.;Dubois, Ph.;Jerome, R.;Ihre, H.;Hult, A.. And the article was included in Macromolecules in 1997.Name: Benzyl 2-hydroxy-2-methylpropanoate This article mentions the following:
Multifunctional poly(caprolactones) with novel and well defined mol. architectures were synthesized by the use of new dendritic initiators. The ring-opening polymerization methods used to prepare these new structures allowed accurate control of mol. weight and narrow mol. weight distributions. In some cases, the new initiators enable deprotection in the α-position of the chain to produce new AB2 macromonomers and their subsequent self-polymerization produces hyperbranched polyesters. The new polymers were characterized by 1H-NMR, 13C-NMR and size exclusion chromatog. (SEC). 13C-NMR spectra clearly shows that the initiators are fully substituted to give polymers with two, four and six arms. In the experiment, the researchers used many compounds, for example, Benzyl 2-hydroxy-2-methylpropanoate (cas: 19444-23-6Name: Benzyl 2-hydroxy-2-methylpropanoate).
Benzyl 2-hydroxy-2-methylpropanoate (cas: 19444-23-6) 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. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Name: Benzyl 2-hydroxy-2-methylpropanoate
