A kind of composition, comprising linking agent and number-average molecular weight is 500-1,000,000 silicon-containing copolymer, this silicon-containing copolymer contained by the formula (I) and (II) the necessary unit of expression, and can comprise the option unit by formula (III)-(VII) expression ,-20-100 ℃ reaction 1-3 hour.Resulting composition is coated in the substrate, and thermofixation under the temperature of 150 ℃ or higher (for example 250 ℃).Therefore all cured articles of excellent silicon-containing polymer of various material properties have been obtained.(in the general formula, A is NH or oxygen, and its ratio Si-O/ (Si-N+Si-O) is 0.01-0.99). |
