Abstract: An exemplary method for making a transparent composite includes steps of combining a refractive index modifier with a precursor solution to provide a modified polymer precursor solution, combining glass with the modified precursor solution, and curing the modified precursor solution to create a transparent glass reinforced polymer composite. An example refractive index modifier comprises a monofunctional compound or monofunctional monomer, a polyfunctional compound or polyfunctional monomer or polymer, which is combined with the polymer precursor solution to increase the crosslinking density of the chain in the cured modified polymer precursor solution, and thus increase the refractive index. An exemplary transparent composite comprises a glass reinforced thermosetting polymer composite layer sandwiched between glass layers.

Abstract: The invention pertains generally to miscible polymer blends which can be used in optical applications, particularly in liquid crystal displays and optical adhesives, in that they are essentially birefiringence-free. The polymeric blend alloy includes a first polymer having an inherent positive birefringence and a second polymer having an inherent negative birefringence, the first and second polymers being soluble within each other to predefined limits. The polymer blend is an essentially birefringence-free film layer suitable for use in liquid crystal displays which has adequate mechanical properties, such as dimensional stability, permeability to water vapor, scratch-resistance and insensitivity to temperature, in that it is possible for them to be processed continuously and flexibly to all the required shapes. The polymer blends can be prepared not only from solvent solutions, but by melt-mixing as well.

Abstract: Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to their microstructure, which gives some of them unusual properties. Numerous novel catalysts are disclosed, as well as some novel processes for making them. The polymers made are useful as elastomers, molding resins, in adhesives, etc. Also described herein is the synthesis of linear .alpha.-olefins by the oligomerization of ethylene using as a catalyst system a combination a nickel compound having a selected .alpha.-diimine ligand and a selected Lewis or Bronsted acid, or by contacting selected .alpha.

The coating composition provides a coating film which is superior in durability. Furthermore, this coating film does not generate an uncomfortable noise even when a glass plate wet with water slides on the coating film.
