Abstract:
The present invention provides a graft or a block polymer in which a fluorine rubber and a silicone rubber are chemically bonded. The present invention is a graft or a block polymer comprising at least one kind of a silicone rubber segment and at least one kind of a fluorine elastomer segment. Furthermore, it is preferable that a fluorine containing elastomer segment is an elastomer segment comprising vinylidene fluoride or an elastomer segment comprising tetrafluoroethylene and that a silicone rubber segment has a unit of dimethylsiloxane and/or methyl-3,3,3-trifluoropropylsiloxane.
