Abstract: PURPOSE: A prepolymer composition for a polymer dispersed liquid crystal is provided to lower production costs because a photoinitiator is not used and to ensure excellent contrast ratio with low driving voltage. CONSTITUTION: A prepolymer composition for a polymer dispersed liquid crystal includes 0.1~20 weight% of polyfunctional oligomer, 0.1~99 weight% of diluents, and 0.1~99 weight% of crosslinking agent. The diluent and cross-linking agent has a composition ratio of 30:1 - 99:1. The polyfunctional oligomer is a urethane-based acrylate derivative compound containing two or more functional groups to which a terminal group is substituted for a hydroxy group. The diluents includes one or more monomer with one functional group selected from alkyl-based acrylate.

Abstract: PURPOSE: A modified polyester resin composition is provided to increase a gas-barrier property through a polyethylene naphthalate resin polymerized by o-phthalic acid and to improve heat resistance by blending polyether imide. CONSTITUTION: A modified polyester resin composition is such that polyetherimide is blended into a polyethylene naphthalate resin in which monomers of o-phthalic acid and dimethyl-2,6-naphthalene dicarboxylic acid are copolymerized in a constant rate. The copolymerization ratio of o-phthalic acid and dimethyl-2,6-naphthalene dicarboxylic is 1-30 mol% and 70-99 mol% respectively.
Abstract translation: 目的：提供改性聚酯树脂组合物，以通过邻苯二甲酸聚合的聚萘二甲酸乙二醇酯树脂提高阻气性，并通过共混聚醚酰亚胺来提高耐热性。 构成：改性聚酯树脂组合物是将聚醚酰亚胺掺合到聚萘二甲酸乙二醇酯树脂中，其中邻苯二甲酸和二甲基-2,6-萘二甲酸的单体以恒定的速率共聚。 邻苯二甲酸和二甲基-2,6-萘二甲酸的共聚比分别为1-30mol％和70-99mol％。
