Abstract: | Copolymers of 4-Cinnamoylphenylmethacrylate (4-CPMA) and acrylamide (AA) were prepared in a ethylmethylketone (MEK) solution
with benzoylperoxide (BPO) as a radical initiator at 70 °C. They were characterized by IR, 1H NMR, and 13C NMR techniques. Copolymer compositions were determined from 1H NMR spectra. The monomer reactivity ratios and the copolymer composition were determined by using Finemann–Ross (F–R) and
Kelen-Tudos (K–T) methods. Thermogravimetric analysis of copolymers reveals that the thermal stability of the copolymer increases
with an increase in the mole fraction of CPMA in the copolymer. The photocrosslinking of the copolymer were studied in solution. |
