Isopropenyl Acetate

Radiation-induced graft copolymerization of vinyl acetate (VAC) and isopropenyl acetate (PAC) onto isotactic polypropylene (IPP) has been studied. The percentage of grafting was calculated for various reaction parameters, and the optimum conditions for attaining the maximum percentage of grafting were determined. Maximal achieved extents of grafting are 39% and 29% for VAC and PAC, respectively. The reactivity of the two monomers with respect to grafting is discussed.

The Fourier Transform

In this study, we report the preparation of Acrylated Palm Oil (APO) nanoparticles using aqueous Cetyltrimethylammonium bromide (CTAB) microemulsion system. This microemulsion system which contains the dispersed APO nanodroplets was subjected to the gamma irradiation to induce the formation of the crosslinked APO nanoparticles. The dynamic light scattering (DLS), the Fourier Transform Infrared (FTIR) spectrocospy and the Transmission Electron Microscopy (TEM) were used to characterize the size and the chemical structure of the nanoparticle. Sized of the APO nanoor microparticle can be varied depended on the volumes of the modified palm oil and the irradiation doses. Their size is in the range of 73 to 100 nanometer (nm) after irradiation using gamma irradiator. This radiation-induced method provides a free initiator induced and easy to control process as compared to the classical or chemical initiator process.
