Title (EN) RADIALLY MULTI-BRANCHED POLYMER AND POROUS FILM USING THE SAME
(FR) POLYMERE A RAMIFICATIONS MULTIPLES RADIALES ET FILM POREUX UTILISANT LEDIT POLYMERE
Abstract: front page image
(EN)Disclosed is a novel radially multi-branched polymer. The radially multi-branched polymer includes a central molecule to which side-branches are bonded in at least three positions and has an average molecular weight of 500 to 100,000, the side-branch being selected from the group consisting of a polyalkylene oxide, a polyacrylate, a polyester, a polyamide and derivatives thereof. The radially multi-branched polymer is used for manufacturing a low dielectric insulating film to provide a low dielectric insulating film having easily controllable micropores.
(FR)L'invention concerne un nouveau polymère à ramifications multiples radiales. Ledit polymère à ramifications multiples radiales comprend une molécule centrale à laquelle sont liées les ramifications latérales, dans au moins trois positions et présente un poids moléculaire moyen de l'ordre de 500 à 1.000, la ramification latérale étant sélectionnée dans le groupe comprenant un oxyde de polyalkylène, un polyacrylate, un polyester, un polyamide et des dérivés desdits constituants. Le polymère à ramification multiples radiales s'utilise pour produire un film isolant à constante diélectrique réduite présentant des micropores aisés à réguler.
