Abstract

Abstract Translated from Japanese (57)【要約】 【解決手段】 下記一般式(1) 【化1】 (式中、nは10〜200の整数である。)で示される 液状ポリブタジエンオリゴマーを部分水素添加反応して 一分子当たり1〜10個の不飽和基を残し、次いで下記 一般式(2) 【化2】 (式中、Rは炭素数1〜12の1価炭化水素基、Xはハ イドライド基、ハロゲン基、アルコキシ基、アシルオキ シ基、ケトキシメート基、アミド基、酸アミド基及びア ミノオキシ基より選ばれる基を示し、aは0,1又は2 の整数である。)で示されるケイ素化合物をハイドロシ リレーション反応させることを特徴とする加水分解性ケ イ素含有ポリオレフィンの製造方法。 【効果】 本発明によれば、空気中の水分で室温で架橋 できる液状の加水分解性ケイ素含有ポリオレフィンを得 ることができ、これは樹脂改質用としてだけでなく弾性 シーリング剤や接着剤の用途にも適用できる。 (57) [Summary] [Solution] The following general formula (1): (In the formula, n is an integer of 10 to 200.) The liquid polybutadiene oligomer represented by the formula (1) is partially hydrogenated to leave 1 to 10 unsaturated groups per molecule, and then the following general formula (2): Chemical 2] (In the formula, R is a monovalent hydrocarbon group having 1 to 12 carbon atoms, X is a group selected from a hydride group, a halogen group, an alkoxy group, an acyloxy group, a ketoximate group, an amide group, an acid amide group and an aminooxy group. , A is 0, 1 or 2 Is an integer. ) A hydrolyzable silicon-containing polyolefin is subjected to a hydrosilylation reaction. [Effects] According to the present invention, a liquid hydrolyzable silicon-containing polyolefin that can be cross-linked at room temperature with water in the air can be obtained, which is used not only for resin modification but also as an elastic sealing agent or adhesive. Can also be applied to.
