Title (EN) ACETYLENE TERMINATED IMIDE OLIGOMERS HAVING IMPROVED SOLUBILITIES AND LOWER MELTING POINTS
(FR) OLIGOMERES IMIDES A TERMINAISON ACETYLENIQUE PRESENTANT DES SOLUBILITES AMELIOREES ET DES POINTS DE FUSION PLUS BAS
Abstract: front page image
(EN)Acetylene-substituted polyimides fabricated from 2,2-bis(3,4-diacarboxyphenyl) hexafluoropropane dianhydride exhibit very low melting points and are soluble in low boiling solvents. The processing characteristics of these oligomers are superior to that of prior art acetylene-substituted imide oligomers.
(FR)Polyimides acetylene substitues produits a partir de 2,2-bis(3,4-diacarboxyphenyle) dianhydride d'hexafluoropropane presentant des points de fusion tres bas et solubles dans des solvants possedant un point d'ebullition bas. Les caracteristiques de traitement de ces oligomeres sont superieures a celles des oligomeres imides acetylene substitues de l'art anterieur.
