摘要：
Polymeric sunscreen particles are prepared from organic monomers such as aldehydes, phenols, amines and carboxylic acids. Polymerization methods include, oxidative polymerization, micro-emulsion polymerization and nucleation-directed polymerization. The particles have the ability to absorb both UVA and UVB radiation. The sunscreens prepared in the present invention are inexpensive and non-toxic and may be prepared from bio-based materials.
