Abstract:
(EN) The objective of the present invention is to provide a biodegradable material having improved flexibility, an increased percentage of shape recovery after the material has been deformed, and improved biodegradability. The present invention provides a biodegradable material resulting from chemically crosslinking: a polyvalent compound (A) having at least three functional groups (X) such as hydroxyl groups; a polyvalent compound (B) having at least three functional groups such as carboxyl groups; and a compound (C) having a structure derived from a hydroxycarboxylic acid and having a glass transition point of the homopolymerized homopolymer thereof of no greater than -40°C.
(FR) L'invention a pour objectif de fournir un matériau biodégradable dans lequel la biodégradabilité est améliorée, le taux de rétablissement de forme après déformation de ce matériau, est amélioré, et la flexibilité est meilleure. Plus précisément, l'invention fournit un matériau biodégradable dans lequel un composé polyvalent (A) possédant au moins trois groupes fonctionnels (X) tels qu'un groupe hydroxyle, ou similaire, un composé polyvalent (B) possédant au moins trois groupes fonctionnels tels qu'un groupe carboxyle, ou similaire, et un composé (C) possédant une structure dérivée d'un acide hydroxycarboxylique dans laquelle le point de transition vitreuse d'un homopolymère ayant subi une polymérisation simple est inférieur ou égal à -40°C, sont soumis à une réticulation.
(JA) 本発明は、生分解性が改善され、かつ材料が変形した後の形状の復元率の向上や、柔軟性が改善された生分解性材料を提供することを目的としている。本発明は、水酸基等の官能基Xを3以上有する多価化合物Aと、カルボキシル基等の官能基を3以上有する多価化合物Bと、単独重合したホモポリマーのガラス転移点が-40℃以下であるヒドロキシカルボン酸由来の構造を有する、化合物Cとが化学架橋されてなる、生分解性材料を提供する。
