POLYAMIC ACID AND POLYIMIDE, PROCESSES FOR THE PRODUCTION OF SAME, COMPOSITIONS CONTAINING SAME, AND USES THEREOF |
摘要 |
<p>The purpose of the present invention is to provide a polyimide resin which exhibits higher heat resistance than that of a conventional polyimide resin by controlling the geometric configuration of the constituent units. Provided is a polyamic acid which comprises repeating units represented by general formula (1), wherein the 1,4-bismethylenecyclohexane skeleton units consist of both trans- and cis-form units, and the contents of the trans- and cis-form units are 60 to 100% and 0 to 40% respectively (with the sum total of the trans- and cis-form units being 100%).</p> |
