Abstract: PURPOSE:To obtain an optical resin having a high refractive index and light resistance, does not discolor upon irradiation with sunlight or heating and does not emit any odor during processing by polymerizing a specified monomer having a thioester group. CONSTITUTION:This optical resin is formed of a polymer of a monomer mixture based on a monomer of formula I (wherein R is a hydrogen atom or a methyl; X is Cl or Br; m is an integer of 0-5; n is an integer of 1-4; and Ar is a benzene ring or a naphthalene ring). It is desirable that at least about 20wt.% monomer of formula I is contained in the total monomer mixture. The monomers other than the monomer of formula I are not particularly limited as far as they are olefinic compounds, and (meth)acrylic compounds, styrene compounds, acrylonitrile, and N-phenylmaleimide are particularly desirable. When a crosslinking monomer is added to the monomer mixture as a comonomer, a resin particularly excellent in heat resistance can be obtained. A desirable crosslinking monomer is one of formula II (wherein X is Cl or Br; and m is an integer of 0-5).

Abstract: PURPOSE:To provide a powdery adhesive for the point bonding of substrates of a liquid crystal display cell to keep the gap between the substrates at a constant distance and composed of an epoxy resin adhesive having a specific particle size and nonspherical form and containing a latent curing agent in the particle in dissolved state. CONSTITUTION:The objective adhesive having minute granular form is composed of an epoxy resin adhesive such as diglycidyl ether of a bisphenol, etc., having an average particle diameter of 1-20mum and nonspherical form and containing a latent curing agent (preferably glycidyl ether derivative of bisphenols, aromatic amines, amines having steric hindrance, etc.) in the particle in dissolved state. A large-sized display can be produced by the use of said adhesive without degrading the quality of the display.

Abstract: PURPOSE:To obtain the title high-grade polymer suitable as, e.g., an additive for cosmetics, toners, etc., by discharging a monomer or an oligomer in the form of fine particles by giving a varied flow rate by applying an alternating voltage to a pressure element, dispersing the fine particles by applying thereto electric charges and curing or polymerizing the particles. CONSTITUTION:A feed solution comprising a monomer comprising an epoxy compound or its oligomer, a curing agent comprising an amine compound and a solvent and having an electric conductivity >=10 OMEGAcm is sent from a feed tank 10 through a means 11 for pressurization, such as a booster pump, and a pipe 12 at a pressure of 1-20kg/cm to a nozzle member 20 and this nozzle is filled with this solution to its fore end. In this state, a pressure element 22 is allowed to contract and expand alternately by applying thereto an alternating voltage of a frequency of 10,000-200,000Hz/s through a means 23 for applying an alternating voltage, whereupon the monomer stream discharged from the fore end of the nozzle can be given a varied flow rate and is discharged outward to form fine particles of uniform particle diameters. At the same time, these particles are dispersed by a application of a D.C. voltage of 1,000-10,000V through a means 24 for applying electric charges, received by a fine particle receiver 30 and cured or polymerized to obtain a fine particulate polymer of a diameter of several to several hundreds mu.
