WebThe simplest definition of a polymer is long chain formed by joining many smaller molecules, called monomers [source: Larsen ]. While a paper chain presents a simple image of a polymer, in practical applications, polymers … WebDSC is a useful tool for studying this phenomenon known as “physical aging”. The initial DSC heating scan of physically aged polymers commonly reveals an endothermic peak near the trailing edge of the Tg step-change. This peak is referred to as the “enthalpy of relaxation” or “enthalpic recovery” (ΔH R ).
