Abstract:
1. A method for the manufacture of a polymerisable multifunctional polymer composition, comprising the steps of: (a) preparing a monomer mixture by mixing 30-99 wt % of a methacrylate terminated dendrimer(s) with 1-70 wt % of a reactive solvent(s); (b) adding 30-99 wt % of the obtained monomer mixture, 0.1-70 wt % of a nanofiller(s) with a particle size of less than 0.1 μm, the nanofiller being an organic nanofiller or organic-inorganic-hybrid nanofiller, and forming a nanofiller phase in polymerisation, 0.1-3 wt % of a polymerisation initiator, an optional catalyst, in an amount of 0.1-3 wt %, and optional additives; (c) mixing the added monomer mixture, the nanofiller(s), the polymerisation initiator, optional catalyst, and optional additives at a temperature of 20-50° C.; and (d) mixing the obtained mixture of step (c) with 60-98% of an inert solvent selected from the group consisting of an alcohol, a ketone, an alkane, and tetrahydrofuran to obtain a dental adhesive or dental coating.
