  • Starch-based graft polymer, process for its preparation, and use thereof in printing inks and overprint varnishes
    Patent number: 6423775
    Abstract: A starch-based graft polymer, a process for its preparation and printing inks and overprint varnishes containing the graft polymer. The graft polymer is based on a derivatized starch or a derivatized starch product as the graft substrate. The starch or starch product is derivatized by one or more bifunctional monomers and grafted, at sites of derivatization, with one ore more ethylene derivatives. The process for preparing the graft polymer involves the provision of an aqueous medium containing dissolved or dispersed starch or dissolved or dispersed starch product. This dissolved or dispersed starch or dissolved or dispersed starch product is subjected to derivatization with one or more bifunctional monomers to prepare a derivatized starch or a derivatized starch product. The derivatized starch or derivatized starch product then is graft-polymerized, at sites of derivatization, with one ore more ethylene derivatives.
