摘要： Disclosed is a transparent plastic sheet obtained by co-polymerizing 100 parts by weight of methyl methacrylate with 0.1 to 2.0 parts by weight of methacrylic acid and 0.1 to 1.5 parts by weight of glycidyl methacrylate, and having a thickness of not greater than 4 inches, wherein the angular deviation satisfies specified conditions according to the thickness of the sheet and wherein the degree of swelling is not greater than 2.50. This transparent plastic sheet shows neither coloring nor sink marks on the surface, has excellent craze resistance and low long-term water absorption percentage, and is hence suitable for use as an aircraft windshield.

摘要： A composition containing a nanosubstance is provided. Since the composition includes a nanosubstance (a), a (meth)acrylate compound (b) including a polar group, and a solvent (c)/polymerizable monomer (i-1), it is capable of being dispersed or solubilized in various solvents such as organic solvents, hydrous organic solvents and in polymerizable monomers without impairing characteristics of the nanosubstance itself wherein the nanosubstance neither separates out nor aggregates during a long-term storage, the composition being excellent in conductivity, film-forming property and moldability and capable of applying to or coating a substrate by a simple method. A coated film or cured film of a composite formed by the composition on at least one surface of the substrate shows high transparency, and the composite is excellent in water resistance, weatherability and hardness.
