WebNov 1, 2006 · For example, in a semi-crystalline polymer, chain scission caused by photo-oxidation, may lead to secondary crystallisation (‘chemi-crystallisation’), increasing density, and causing an increase in Young’s modulus and reducing ductility. Similar effects may be observed in glassy polymers, due to chain scission accelerating physical ageing.
