The author of the article were Lamboley, Serge; Trachsel, Alain; Herrmann, Andreas. The article conveys some information:
Light-sensitive 2-oxoacetate-derived polystyrene copolymers are investigated for the controlled release of fragrances. The stimuli-responsive delivery systems are efficiently prepared in a two-step reaction sequence. Simultaneous Friedel-Crafts acylation and cationic polymerization of styrene give access to 2-oxoacetate-derived polystyrenes in one step; the fragrance to be released is then introduced by organotin-catalyzed transesterification in a second step. The performance of the copolymer conjugates releasing either individual fragrance raw materials or a fragrance mixture is evaluated by dynamic headspace anal. in the presence of surfactants on different substrates and compared with their non-polymeric analogs. Direct and indirect deposition of the delivery systems onto cotton in a fabric softening application show that differences in performance are correlated with the amount of surface deposition. In the present study, the copolymer that releases a fragrance mixture performs better than the copolymers that release the corresponding fragrances individually and better than the resp. non-polymeric profragrances. The experimental part of the paper was very detailed, including the reaction process of Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3Related Products of 5781-53-3)
Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.Related Products of 5781-53-3
