ELASTOMERIC COPOLYIMIDES CONTAINING FLUORINE AND PROCESS FOR PREPARING SAME |
摘要 |
<p>A new class of elastomeric copolymers the chains of which contain perfluoropolyether radicals having a linear structure linked through cycloimide groups to organic radicals of different and suitable structure is disclosed, as well as a process for preparing such copolymers which comprises condensing a mixture of fluorinated polyether diamines with one or more tetracarboxylic dianhydrides or esters.</p> |
