Using a method of infiltrating alkoxysilane monomer , the autor uses 4-step process emulsion prepared with a narrow distribution,strawberry, multi-layer core-shell structure and morphology of latex particles, including acrylic esters as the main monomer, while infiltration of A-174 as a monomer into polymer systems, thus prepared strawberry core-shell structure of latex particles.Using TEM, DLS analysis of the latex particles ,in the TEM picture, latex particles can be clearly seen with the strawberry core-shell structure; emulsion core-shell particles are DLS data further confirmed that the multi-layered core-shell latex particles structure; and obtained by the DLS analysis of the diameter of latex particles and obtained with the TEM photographs correspond to the data.

With the method of infiltrating alkoxysilane monomer and in the process of 4-step emulsion polymerization, we have prepared  latex particles with narrow distributional,strawberry-type, multi-layer core-shell-like structure. In addition, we have prepared strawberry-type and core-shell-like structural latex particles by using acrylic esters as the main monomer and infiltrating the £Á-174 monomer into the system of polymerization.The TEM and DLS are applied to analyze the morphology of  latex particles. In the micrograph of TEM,  the strawberry-type and core-shell-like structure could be definitely identified, and core-shell-like structure could be further  confirmed by DLS analysis, namely  latex particles have the multi-layered core-shell-like struture. The values of the diameter of latex particles obtained by  DLS analysis is consistent with ones obtained from the micrograph of TEM.
