Abstract
There is an increasing interest in polymeric bulk materials with a profile of mechanical, optical and thermal properties adapted to specified applications. To provide such materials, the multifunctional (meth)acrylate alkoxysilanes have been developed as precursors for the sol-gel process and therefore, for the preparation of inorganic-organic copolymers. Bulk materials based on the previously described thioether (meth)acrylate alkoxysilanes, as a class of the new silane type, already show a wide variety of adjustable properties. In order to achieve polymeric materials with higher modulus of elasticity, higher flexural strength and lower thermal expansion coefficient a further family of the above mentioned silane type, the urethane (meth)acrylate alkoxysilanes, has been developed to widen the possible range of properties.
