Abstract:
(EN) Provided is a modified polytetrafluoroethylene having excellent breaking strength. The modified polytetrafluoroethylene contains a polymer having a unit based on tetrafluoroethyelene and a polymer having a unit based on the monomer represented by formula (1), the content of the unit based on the monomer represented by formula (1) is 10-500 ppm by mass relative to all the units in the modified polytetrafluoroethylene, and the standard specific gravity of the modified polytetrafluoroethylene is 2.155-2.175. Formula (1): CH2=CR1-L-R2. R1 represents a hydrogen atom or an alkyl group. L represents a single bond, -CO-O-*, -O-CO-*, or –O-. * represents a bonding position with R2. R2 represents a hydrogen atom, an alkyl group, or a nitrile group.
(FR) L'invention concerne un polytétrafluoroéthylène modifié présentant une excellente résistance à la rupture. Le polytétrafluoroéthylène modifié contient un polymère ayant une unité à base de tétrafluoroéthanediène et un polymère ayant une unité à base du monomère représenté par la formule (1), la teneur en unité à base du monomère représenté par la formule (1) est de 10 à 500 ppm en masse par rapport à toutes les unités dans le polytétrafluoroéthylène modifié, et la gravité spécifique standard du polytétrafluoroéthylène modifié est de 2,155 à 2,175. Formule (1) : CH2=CR1-L-R2. R1 représente un atome d'hydrogène ou un groupe alkyle. L représente une liaison simple,-CO-O-*, -O-CO-*, ou -O-. * représente une position de liaison avec R2. R2 représente un atome d'hydrogène, un groupe alkyle ou un groupe nitrile.
