Synthesis and polymerization of 2‐vinyl‐4,4‐dimethyl‐5‐oxazolone

Chemistry and technology of 2‐alkenyl azlactones

“…The glass‐transition temperatures ( T g 's) for p(VDMA) and p(IDMA) are 92 and 165 °C, respectively 13. These temperatures, however, are not particularly important from a practical point of view because the intent in copolymerizing 2‐alkenyl azlactones is essentially always as an intermediate step in an overall polymer‐modification procedure.…”

History of Post‐Polymerization Modification

“…Polymers bearing pendant oxazoline groups can be prepared by the polymerization of 2-vinyl-4,4-dimethyl-5-oxazoline (VDM), which was first illustrated by Taylor and coworkers in the early 1970s [60]. Similar to MAn copolymers, quantitative modification of polyVDM with amines is possible at room temperature [47,48].…”

A Novel Route to α,ω ‐Bis(acrylamidopeptide)‐Terminated Oligo(ethylene oxide) and Hydrogels

“…[7] Then the azlactone was obtained by reaction with ethylchloroformate in anhydrous hexane in the presence of an equimolar amount of triethylamine as described in the literature. [8] Mp. 29 8C; the pysical data are in accordance with those previously reported.…”

“…29 8C; the pysical data are in accordance with those previously reported. [8] Preparation of 4,4-Dimethyl-2-vinyl-oxazol-5-on a-Aminoisobutyric acid was acylated with acryloyl chloride in aqueous NaOH solution. The azlactone was obtained by reaction with ethylchloroformate in anhydrous hexane in the presence of an equimolar amount of triethylamine.…”

“…6 8C; the pysical data are in accordance with those previously reported. [8] Preparation of (Meth)acrylamidopeptide-Terminated PEO PEO2 and PEOII were used as a,x-diamino-terminated PEO, and PEO1 as the x-monoamino-terminated PEO, were used without further purification. The compositions of the Jeffamines are listed in Table 1.…”
