Thermo-mechanical properties of oriented cycloaliphatic polyimides

Cyclo-aliphatic polyimides were synthesized from stereoisomeric dianhydrides of 1,2,3,4-cyclohexane tetracarboxylic acid with cis- and trans-arrangement of anhydride rings in relation to the plane of the cyclohexane ring and a number of aromatic diamines: p-phenylenediamine, benzidine, 4,4′-diamondi...

Description
Summary:Cyclo-aliphatic polyimides were synthesized from stereoisomeric dianhydrides of 1,2,3,4-cyclohexane tetracarboxylic acid with cis- and trans-arrangement of anhydride rings in relation to the plane of the cyclohexane ring and a number of aromatic diamines: p-phenylenediamine, benzidine, 4,4′-diamondiphenyloxide and 4,4′-diaminodiphenylmethane. A study was made of thermo-mechanical properties of oriented model monofilaments prepared from the polyimides indicated. The effect of the chemical structure of polyimides on structure and physico-mechanical properties was investigated over a wide range of temperature.
