Abstract

Official abstract text for this publication.

Disclosed is a triazine ring-containing hyperbranched polymer containing a repeating unit structure represented by the expression (1). By this means, it is possible to achieve a triazine ring-containing polymer which, alone, has high heat resistance, high transparency, high refractive index, high light resistance, high solubility, low volume shrinkage without adding metal oxides; and also a membrane-forming composition containing the same. In the formula, R and R′ represent independently a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and A represents an alkylene group optionally having a branched or alicyclic structure of 1 to 20 carbon atoms.

First claim

Opening claim text (preview).

The invention claimed is: 1. A film consisting essentially of a triazine ring-containing hyperbranched polymer characterized by comprising a recurring unit structure of formula (1) below wherein R and R′ are each independently a hydrogen atom or an alkyl, alkoxy, aryl or aralkyl group; and A is an alkylene group which may have an alicyclic structure of 1 to 20 carbons and is at least one moiety selected from the group consisting of moieties of formulas (2) to (14) below R 1 and R 2 being each independently an alkylene group which may have a branched structure of 1 to 5 carbons, and wherein the polymer is capped on at least one end by an alkyl, aralkyl, aryl, alkylamino, alkoxysilyl-containing alkylamino, aralkylamino, arylamino, alkoxy, aralkyloxy, aryloxy or ester group, wherein the hyperbranched polymer has a weight-average molecular weight of between 400 and 10,000. 2. The film according to claim 1 , wherein A has formula (2). 3. The film according to claim 1 , wherein the recurring unit structure of the polymer has formula (15) below 4. The film according to claim 1 , wherein the recurring unit structure of the polymer has formula (16) below 5. The film according to claim 1 , wherein the polymer has at least one terminal triazine ring which is capped by an alkyl, aralkyl, aryl, alkylamino, alkoxysilyl-containing alkylamino, aralkylamino, arylamino, alkoxy, aralkyloxy, aryloxy or ester group. 6. An electronic device comprising a base material and the film of claim 1 formed on the base material. 7. An optical member comprising a base material and the film of claim 1 formed on the base material. 8. A solid-state image sensor formed of a charge-coupled device or complementary metal oxide semiconductor, which sensor comprises at least one layer of the film of claim 1 . 9. A solid-state image sensor comprising the film of claim 1 as a planarization layer on a color filter.
