Synthesis of Carboxymethyl Cellulose-Acrylate-OvPOSS Graft Copolymer and its Application in Paper Protection

As an important part of cultural heritage, paper relics have historical, scientific and humanistic values. However, a large number are suffering from aging, mildew, yellowing, cracks, embrittlement other threats, or even completely damaged. To enhance the strength prolong life relics, novel CMC-acrylate-OVPOSS graft copolymer was synthesized with carboxymethyl cellulose (CMC), methyl methacrylate (MMA), butyl acrylate (BA), hydroxyethyl (HEMA), glycidyl (GMA), octavinyl polyhedral oligomeric silsesquioxane (OVPOSS). The materials were analyzed by infrared spectroscopy, X-ray diffractometer, thermal analyzer photoelectron spectroscopy. In addition, reinforcement solution coated on surface paper, protective effect evaluated testing mechanical optical properties paper. When mass concentration 10 % greatly improved, gloss whiteness basically unchanged.
