Claims16
A vinylidene fluoride polymer comprising more than 50% moles of recurring units derived from the polymerization of vinylidene fluoride monomer, said polymer (VDF) being characterized by having a size distribution with a D50 value higher than 250 microns.
A process for manufacturing a vinylidene fluoride polymer in aqueous suspension, said process comprising polymerizing vinylidene fluoride monomer (VDF monomer) from a polymerization reaction mixture comprising:
- A) at least a non-ionic suspending agent present in the polymerization reaction mixture in an amount of from 0.01 to 2 g per kg of VDF monomer;
- and
- B) at least an ionic carboxyalkyl cellulose.
