Abstract: A new type of polymeric particles with hydrophobic hairs of PLA was prepared via initiating ring-opening polymerization(ROP) of D,L-lactide from the polymeric core particles of polystyrene and poly(2-hydroxyethyl methacrylate)[poly(St-co-HEMA)]. Successful grafting and well-dispersible properties of the hairy particles were approved via thermogravimetric analysis(TGA), scanning electron microscopy(SEM) and Fourier transform infrared analysis(FTIR). The experimental results indicate that this grafting procedure is effective and controllable for the preparation of novel hydrophobic hairy particles. The presence of hairy shell on core particles resulted in dramatic improvement of its dispersibility in organic solvent.

Key words: Hydrophobic hairy particle, D,L-Lactide, Ring-opening polymerization, Dispersibility, Grafting efficiency
