Abstract
The invention concerns a process for preparing composite resin particles having the so-called semi-IPN (inter penetration network) structure, in which linear thermoplastic polymer chains get entangled with a crosslinked polymer core through partial or thorough penetration. This method is very important in that both of the chain polymer and core polymer are freely selected from various resins.
