WitrynaIn materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer ( resin ). [1] Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst. cannot use command prompt windows 10WitrynaQuestion: What does “imidized” mean about the chemical structure of a polymer? flag football activities for middle schoolWitryna1 sie 2006 · The imidization process consists of cyclodehydration of PAA to form linear, stiff, ordered PI chains. As the rigid cyclic imide structure is formed during the imidization the chain mobility is decreased due to increase in stiffness. flag football abqWitrynapolyamic acid and pre-imidized polyimide solu-tions. A classical way to identify the conduction mechanism is to examine linearity in J–E curves. The plot consists of two regions, in the lower region of the applied electric field, the slope is around 1, and in the higher region, the slope is around 2.
