摘要：

Poly(n-butyl acrylate-co-methyl methacrylate) particles encapsulated with chitosan were synthesized at In monomer ratio using potassium persulfate as an initiator. Effect of concentration and molecular weight of chitosan on particle encapsulation process was investigated. Chitosan concentration was varied from 0.5%, 1%, and 1.5% w/v, while molecular weights were 120, 370, and 850 kDa, respectively. The results showed that the particle diameter of the copolymer particles with chitosan encapsulation was increased when the concentration and molecular weight of chitosan were increased. The average particle size and zeta potential were obtained in a range of 144-625 nm and +27 - +47 mV, respectively. TEM micrographs suggested a presence of the chitosan encapsulation layer on the particles.
