Abstract
It is possible to provide the heat resistant material and coating material for OA equipments which comprise a fluorine-containing multi-segment polymer having heat resistance, abrasion resistance, non-sticking property against toner and oil resistance in addition to flexibility and are used particularly on surfaces of fuser roll and belt. Those materials comprise a fluorine-containing multi-segment polymer having an elastomeric fluorine-containing polymer chain segment A and a non-elastomeric fluorine-containing polymer chain segment B, and the elastomeric fluorine-containing polymer chain segment A comprises not less than 90% by mole of perhaloolefin unit as a recurring unit and imparts flexibility to the whole polymer.
