发明名称 Wrinkled polyester particles
摘要 The present invention comprises wrinkled polymer particle comprising a polyester-containing particle having a surface covered with at least one wrinkle comprising folds, ridges, crevices and channels. The present invention further comprises a method of forming wrinkled polyester-containing particles comprising preparing a mixture of an organic phase and an aqueous phase, said mixture comprising an unsaturated precursor polyester, a water immiscible organic solvent, at least one organic-soluble ethylenically unsaturated monomer, and initiator, subjecting said mixture to high energy emulsification, initiating crosslinking of said polyester after emulsification, and removing said water immiscible organic solvent to recover wrinkled polyester-containing particles.
