摘要： A mask for a selective growth of a solid, is provided in which the solid is selectively grown in a predetermined region of a substrate and growth on other regions is suppressed. A method is also provided for selectively growing a solid on only the predetermined region of a substrate using the mask. In the mask, a surface layer and an underlayer are provided, each having different chemical compositions. Thus, even if the mask is formed on a substrate in an ultra thin film, the generation of mask defects can be suppressed and stability provided to heat and electron beams.

摘要： A process for preparing a thermosetting organopolysiloxane which is soluble in an organic solvent, comprising subjecting to a hydrolyzing condensation reation one or a mixture of two or more alkoxysilanes having the formulaR.sub.a.sup.1 Si(OR.sup.2).sub.4-ain which R.sup.1 is selected from the group consisting of alkyl, substituted alkyl, alkenyl and aryl; R.sup.2 is alkyl having 1 to 4 carbon atoms; and a is an integer of 0, 1 or 2, in the presence, from the initial stage of the reaction, of a hydrolzyed partial condensation product of trialkoxysilane having the above-identified formula in which a is 1.

摘要： A method of promoting the growth of plants which comprises applying to the surface of a plant growth medium to be exposed to a source of ultraviolet radiation a light-degradable mulching film for agricultural use, comprising a resin composition, whose resin components consist essentially of(1) from 5 to 50 percent by weight of polyisobutylene oxide resin,(2) the balance of a second resin component selected from the group consisting of at least one polyolefin resin and a mixture of at least one polyolefin resin and at least one polydiene resin.The resin composition can be made into a mulching film which, when exposed to the sunlight, photolytically degrades into a pulverized condition within a selected period of time.
