Abstract: Disclosed herein is an organic polymer semiconductor compound, a method of forming an organic polymer semiconductor thin film using the same, and an organic thin film transistor using the same. Example embodiments of this invention pertain to an organic polymer semiconductor having a side chain including a removable substituent, and to an organic thin film transistor using the organic polymer semiconductor for an organic active layer, which has lower leakage current, higher charge mobility, and/or a higher on/off ratio.

Abstract: A new adhesive coating composition, particularly for use on airbag fabrics, which is composed of a silicone polymer and an appreciable level of a copolymer of ethylene and a polar monomer, is provided. This coating provides excellent adhesive properties to the coated fabric and provides a synergistic effect such that lower gas permeability upon inflation may be obtained with this coating than might be achieved with the silicone polymer alone. Additionally, such a coating allows maximization of the adhesion characteristics on one-piece woven airbag fabric such that blistering upon high-pressure inflation can be reduced, while retaining a high degree of inflation gas retention. Fabric treated with this material in the manner described herein permits reduction in the cost of the coating itself (by reducing the use of expensive silicone polymers). Airbag fabrics and cushions, as well as methods of making and using such a novel airbag coating material are also encompassed within this invention.

Abstract: A novel process for coupling living polymers containing terminal (meth)acrylic units, which enables an increase in molecular weight and/or a defined multisequencing and/or a star structure with a defined number of branches, is disclosed. The disclosed process comprises the steps of: (i) anionic polymerization using an initiator system consisting of a functional initiator and a ligand to obtain a living polymer containing living terminal (meth)acrylics units; (ii) reacting it with an aldehyde compound of formula R--(CHO).sub.r in which r.gtoreq.2; and (iii) recovering the final polycondensate by means known per se.

Abstract: A photopolymerizable composition comprising (a) an addition polymerizable compound having a boiling point of 100.degree. C. or high under an atmospheric pressure, (b) a photoinitiator, and (c) a benzene derivative can provide a cured film having high strength suitable for producing, e.g. printed circuit boards.

Abstract: The crosslinking of unsaturated polyester resins at room temperature in the presence of a peroxyester initiator is accelerated by a mercapto compound and a metal salt wherein the metal is selected from the group consisting of copper, and iron, or a mixture of the metal salts.
