Abstract: front page image
(EN)Polyimide and polyamic acid exhibiting no absorption in the ultraviolet region, exhibiting high light transmittance and excelling in solubility in organic solvents. The polyamic acid and polyimide can be obtained from a diamine and a tetracarboxylic acid dianhydride of specified structure having an aromatic ring and an alicyclic structure. This tetracarboxylic acid dianhydride of specified structure having an aromatic ring and an alicyclic structure, as shown in Fig. 1, is a tetracarboxylic acid dianhydride obtained through Diels-Alder reaction from, as raw materials, 2 mol of malic anhydride or its derivative and 1 mol of diphenylethylene or its derivative, or is a hydrogenation product thereof. In particular, this hydrogenation product has its carbon to carbon double bond portion, formed by the Diels-Alder reaction, hydrogenated, and hence is a stable compound with which any inverse Diels-Alder reaction in high temperature environment is suppressed.
(FR)L'invention porte sur un acide polyamique et sur une polyimide sans absorption de la région UV, à forte transmittance de la lumière et d'une excellente solubilité dans les solvants organiques. L'acide polyamique et la polyimide s'obtiennent à partir d'une diamine et d'un dianhydride de l'acide tétracarboxylique, de structure spécifique, présentant un cycle aromatique et une structure alicyclique (fig1). Ledit dianhydride s'obtient par une réaction de Diels-Adler entre les matériaux de départs suivants: 2 moles d'anhydre malique ou ses dérivés et 1 mole de diphényléthylène ou ses dérivés ou l'un de ses produits d'hydrogénation. Ledit produit d'hydrogénation, présente une double liaison carbone carbone résultant de la réaction de Diels-Adler hydrogénée, il est donc stable et ne peut subir de réaction de Diels-Adler inverse dans un environnement à haute température.
