Core-shell spheroidal microparticles with polystyrene cores and rich in polyglycidol shells

This paper describes the preparation of spheroidal polystyrene core and polyglycidol-rich microparticles by stretching the relevant core-shell microspheres embedded into the poly(vinyl alcohol) film. The requirements for the preparation of the defect-free core-shell spheroids were determined. The rearrangement of the microparticle interfacial layer accompanying the conversion of the microspheres into microspheroids is described.
