The intrinsically-conducting type of these substances is used in OLEDs. In these substances, the glass transition temperature measures the point at which parts of it start sliding past one another, and differential scanning calorimetry is often used to find that temperature. In structural formulas, these are written with a segment in parentheses and a subscript "n", and they can be described as chain-growth or step-growth. Ones that can be remolded upon heating, like PVC, are called thermoplastic. One biological one that is produced by a branching enzyme is starch. For 10 points, name these compounds that are made of
