Provided is a degradable microparticle with a grain size in a range of 2 micrometers to 1400 micrometers, and the degradable microparticle comprises poly(glycerol sebacate), poly(glycerol maleate), poly(glycerol succinate-co-maleate), poly(glycerol succinate), poly(glycerol malonate), poly(glycerol glutarate), poly(glycerol adipate), poly(glycerol pimelate), poly(glycerol suberate), poly(glycerol azelate), or any combination thereof. A degradable product produced from the degradable microparticles can obtain the desired degradation effect and can be produced by chemical synthesis to reduce the production cost. With these advantages, the applicability of the degradable microparticles is improved.
