| Abstract: | The free emulsion polymerization of vinyl acetate in the presence of alumino siloxane sol has been investigated. The dynamic results show that the rate of polymerization of vinyl acetate increases with the increase of the stability of the system of the free emulsion polymerization. IR indicates that there is chemical bonding between aluminosiloxane sol and PVAc. SEM shows that inorganic particles are good covered by PVAc, the width of the glass transition region of the polymer in polymer aluminosiloxane sol systems determined by DSC measurements is not influenced by the amount of the aluminosiloxane sol. |
