A catalyst element for accelerating crystallization is added to an amorphous silicon film containing an impurity element for threshold voltage control, and a heat treatment is then performed to obtain a crystalline silicon film. Thereafter, the catalyst element is gettered by performing a heat treatment in an atmosphere containing a halogen element. In this step, a chemical equilibrium state is established for the impurity element for threshold voltage control by mixing a compound gas containing the impurity element into the atmosphere, thereby preventing the impurity element from escaping into the vapor phase.

The invention provides a method of producing a reactive silicon group-containing polyether oligomer which comprises reacting (a) a polyether oligomer having main chain of a polyether and, in each molecule, at least one unsaturated group represented by the general formula (1):(in the formula, R1 is a hydrocarbon group containing not more than 10 carbon atoms and R2 is a divalent organic group containing 1 to 20 carbon atoms and one or more species selected from the group consisting of hydrogen, oxygen and nitrogen atoms as a constituent atom) or the general formula (2):on a side chain or at a terminus with (b) a reactive silicon group-containing compound in the presence of (c) a group VIII transition metal catalyst to introduce the reactive silicon group into said polyether oligomer (a),wherein the reaction is carried out in the presence of (d) a sulfur compound.

A process for producing a finely cellular polyurethane foam by mixing a first ingredient comprisi an isocyanate compound and a second ingredient comprising a compound containing an active hydrogen group, characterized by comprising adding a nonionic silicone surfactant containing no hydroxyl group to at least one of the first ingredient and the second ingredient in an amount of 0.1 to 5 wt %, excluding 5 wt %, based on the total amount of the first ingredient and the second ingredient, subsequently agitating the surfactant containing ingredient together with an unreactive gas to disperse the unreactive gas as fine bubbles to prepare a bubble dispersion and then mixing the bubble dispersion with the remaining ingredient to cure the resultant mixture. Thus, a polyurethane foam having uniform fine cells and a higher hardness than ones having the same density can be produced without using a chemically reactive blowing agent such as water, vaporizable expandable blowing agent such as fluorocarbon, or other substance such as a finely particulate hollow foam or solvent soluble substance.

This invention relates to a method of preparing poly(alkylene carbonate) that has a molecular weight and polymer chain structure precisely controlled by adding a chain transfer agent composed of a compound having an alcohol or carboxylic acid functional group upon alternating copolymerization of an epoxide compound and carbon dioxide using a catalyst composed of a trivalent metal complex compound synthesized from a quaternary ammonium salt-containing Salen type ligand, and to a polymer compound prepared thereby. According to this invention, the polymer compound having a star-shaped chain as well as the polymer having a linear chain can be prepared. The low-molecular-weight poly(alkylene carbonate) has an —OH terminal group and can be used alone as a coating agent, etc., and also in mixtures with an isocyanate compound and thus can be easily utilized to prepare polyurethane.

An anaerobic adhesive composition includes a monomer curable upon exclusion of oxygen. A peroxy polymerization initiator is present within the composition. The composition has a thixotrope imparting a thixotropic viscosity ratio in an uncured state of 8.2:1 to 11:1 as measured at rotation rates of 0.5 and 10 revolutions per minute. The thixotrope is composed of 3 to 50 total weight percent of inorganic particulate or 3 to 36 total weight percent of an organic compound. A process for forming an adhesive bond includes applying to a fastener an anaerobic adhesive composition that includes a polymerizable acrylate ester or vinyl ether, a peroxy polymerization initiator, and a thixotrope. The composition has a thixotropic viscosity ratio of between 8.2:1 and 11:1 for spindle rotation rates of 0.5 and 10.0 revolutions per minute. Tightening the fastener against a substrate induces viscosity breakdown and under the force to cure.
