Preferred Label : main-chain scission;
IUPAC definition : Chemical reaction that results in the breaking of main-chain bonds of a polymer molecule.;
Scope note : some main-chain scissions are classified according to the mechanism of the scission
process: hydrolytic, mechano-chemical, thermal, photo-chemical, or oxidative scission.
others are classified according to their location in the backbone relative to a specific
structural feature, for example, a-scission (a scission of the c–c bond alpha to the
carbon atom of a photo-excited carbonyl group) and ß-scission (a scission of the c–c
bond beta to the carbon atom bearing a radical), etc.;
Origin ID : MT07140;
