Structured latex particles with a slightly crosslinked poly(styrene-n-butyl acrylate) (PSB) core and a poly(styrene-methacrylate-vinyl triethoxide silane) (PSMV) shell were prepared by seed emulsion polymerization; and the latex particle structures were investigated with Fourier transform infrared; thermogravimetric analysis; differential scanning calorimetry; transmission electron microscopy; and dynamic light scattering. The films that were formed from the structured core (PSB)-shell (PSMV) particles under ambient conditions had good water repellency and good tensile strength in comparison with films from structured core (PSB)-shell [poly(styrene-methyl methyacrylate)] latex particles; this was attributed to the self-crosslinking of CH 2=CH-Si(OCH2CH3)3 in the outer shell structure. The relationship between the particle structure and the film properties was also investigated in this work. © 2006 Wiley Periodicals; Inc;
