| Abstract: | Copolymerization of acrylic acid,octadecyl acrylate and vinylpyrrolidone was carried out in supercritical carbon dioxide medium by explosive polymerization.The structure and solution properties of the copolymer were studied by scanning electron microscopy,FT-IR,Ubbelohde viscometer and rotational viscometer.The effect of pressure and composition in feed on reaction was discussed.It shows copolymerization with vinylpyrrolidone is observed to produce explosive polymerization.The reaction can be proceed by decreasing temperature.The yield of copolymer is above 95%.The product was obtained in the form of a white powder and aggregates of particles in size of about 1μm.The copolymer solution has excellent viscosity in low concentration. |
