ABSTRACT:
A copolymer comprising monomeric units derived from ethylene, tetrafluoroethylene and a fluorine-containing vinyl monomer which provides the copolymer with side chains having at least one carbon atom, wherein the molar ratio of tetrafluoroethylene and ethylene is from 62:38 to 90:10 and the content of the fluorine-containing vinyl monomer is from 0.1 to 10% by mole based on the total number of mole of ethylene and tetrafluoroethylene, which has improved flexibility and better flame retardance.
