Anovel core/shell latex particle was successfully prepared by seeded emulsion
polymerization. The rubbery core was made of poly (butyl acrylate) (PBA) with a
slight cross-linked structure, while the glassy shell was poly (methyl methacrylate)
(PMMA) containing a small amount of itaconic acid (ITA). The resulting core/shell
latex particle PBAlP(MMA-ITA) should possess the function both of toughening the
PBA core and the compatibilization of P(MMA-ITA) shell as well. The latex particles
were characterized by transition electron microscopy (TEM), Fourier transform infrared
spectroscopy (FTIR), differential scanning calorimetry (OSC) and non-aqueous acidbase
titration . The results showed well-defined core/shell morphology with the diameter
of 50-65 nm and the cross-linkers diethylene glycol diacrylate (OEGOA), diallyl
phthalate (OAP), and trihydroxymethylpropyl triacrylate (TMPTA) appeared the highest
cross-linking efficiency. The monomer ITA has copolymerized with MMA successfully,
and P(MMA-ITA) copolymer has been linked onto the surface of PBA core both by
chemical bond and physical adsorption. The PBAlP(MMA-ITA) latex particles were
core/shell structure indeed, and varying the ITA dosage and core/shell proportion, its
size, Tgי and ITA content in shell layer would change relatively
