摘要
Poly(vinyl alcohol-g-styrene) graft copolymers with various polystyrene contents (from 9 to 51 mol%) were synthesized. These graft copolymers formed poly(vinyl alcohol) (PVA) core-polystyrene (PS) corona micelles in tetrahydrofuran (THF)-dimethylsulfoxide mixtures when the THF content was from 66 to 69 vol%. The PVA cores of these micelles were crosslinked with terephthal aldehyde (TPA) in solution. When the TPA concentration in relation to vinyl alcohol groups was below 10 mol%, it was possible to hinder intermicelle crosslinking and PVA core-PS shell type microspheres were obtained. The minimum PS shell content of microspheres obtained in this work was 9 mol%.
