The present invention relates to a method for liquid crystal display element without substrates, which comprises applying a release agent to assisting substrates in the process of producing the liquid crystal display so that the assembled liquid crystal display element can be separated from the assisting substrates and the liquid crystal display element is obtained, wherein said release agent comprises (a) 2-20 wt % of compounds selected from the group consisting of silicone, fluorine compounds and mixtures thereof; (b) 0.01-0.6 wt % of release modifier; and (c) a solvent as a complement to 100 wt %.

Method for producing liquid crystal display element without substrates

The present invention provides a metal salt-containing resin composition, which comprises (a) a hydrophilic polymer which is a polymer or copolymer of an ethylene oxide-containing monomer, and (b) 0.1 to 30% of a metal salt, based on the weight of the hydrophilic polymer. The resin composition of the present invention has long lasting antistatic properties and a lower surface resistivity than the hydrophilic polymer alone.

A reactive and durable anti-static agent and the method of preparing the anti-static agent comprises: a compound with an amine group and a compound with an epoxide group added into the flask, stirred under the gradual raised temperature, reacted into an anti-static agent with a reactive functional group under proper temperature. The characteristics of the invention is that the reaction of preparing the anti-static agent is very active, and the preparing method is easy. With the reactive functional groups and polymer additives which enable the reaction in polymer, in addition to the endurance and a long lifetime, the surface property of the anti-static agent is improved. Therefore, the anti-static prepared according to the invention is broadly in use of industry.

A polyetheresteramide compound and the method of preparing it comprise: a polyether compound containing a diamino group at the end mixed with a diacid and a diol, and being polymerized and condensed to form a polyetheresteramide compound. This polyetheresteramide is a durable anti-static resin. In addition to the anti-static property, the polyetheresteramide compound has the physical properties of the original polyester. Thus, the polyetheresteramide compound can be added into an anti-static resin and applied in general resin industry, special chemical and spinning industries. The anti-static products, such as the anti-static thin plate, anti-static bag, IC cover tape, anti-static clothes, and dustless clothes, or even broadly applied in electronic communication, semiconductor, and optoelectronic manufactures.

The present invention provides a functional group-containing alkyl acrylate-butadiene-aromatic vinyl compound copolymer which is obtained from the following layers by emulsion graftlinking polymerization: an inner layer comprising polybutadiene or an aromatic vinyl compound-butadiene copolymer; a middle layer comprising an aromatic vinyl compound-an alkyl acrylate copolymer; and an outer layer comprising an alkyl acrylate-a functional group-containing vinyl compound copolymer. The functional group-containing alkyl acrylate-butadiene-aromatic vinyl compound copolymer can be incorporated into a PC/PBT alloy as an impact modifier, thus the impact strength of the modified alloy composition at room temperature and low temperatures can be increased effectively.

The present invention provides a functional group-containing alkyl acrylate-butadiene-aromatic vinyl compound copolymer which is obtained from the following layers by emulsion graftlinking polymerization: an inner layer comprising polybutadiene or an aromatic vinyl compound-butadiene copolymer; a middle layer comprising an aromatic vinyl compound--an alkyl acrylate copolymer; and an outer layer comprising an alkyl acrylate--a functional group-containing vinyl compound copolymer. The functional group-containing alkyl acrylate-butadiene-aromatic vinyl compound copolymer can be incorporated into a PC/PBT alloy as an impact modifier, thus the impact strength of the modified alloy composition at room temperature and low temperatures can be increased effectively.

The invention relates to a process for preparing gas separation membranes or modules. Membrane forming material is cast into a wet membrane which is wound into a spiral module. The spiral module is arranged in a closed circulating apparatus. Exchanging solvents or treating solutions are circulated through the circulating apparatus and the spiral module for an appropriate period of time. The module and circulating apparatus are purged until the membrane is dry, thus producing a gas separation membrane or module.
