摘      要：According to the new method of preparing core-shell nanospheres developed by our group,by using two monomers,2-hydroxypropyl methacrylate(HPMA) and vinyl acetate(VAc),two kinds of core-shell nanospheres with poly(ε-caprolactone) (PCL) as the core and crosslinked poly(2-hydroxypropyl methacrylate) (PHPMA) or poly(vinyl acetate) (PVAc) as the shell were successfully prepared under similar *** degrading the PCL cores of the two kinds of nanospheres by lipase,the corresponding crosslinked poly(methyl acrylic acid) hollow spheres and crosslinked poly(vinyl alcohol) hollow spheres were *** indicate that the new method we proposed for preparing core-shell polymeric nanospheres via in-situ polymerization can be generalized to a certain extent,and it is suitable for many systems provided the monomer used is soluble in water,while its corresponding polymer is insoluble in water.
