Abstract

A találmány tárgyát képezi egy olyan polimer keverék, amelyizobutilén-alapú polimert és félig kristályos etilén kopolimerttartalmaz, ahol a félig kristályos etilén kopolimer etilénből származótartalma a félig kristályos kopolimer össztömegére vonatkoztatvalegalább 45 tömeg% és a kikeményített keverék légáteresztő képességekevesebb mint 8 x 10-8[cm3-cm/cm2-sec-105 Pa] 65 °C hőmérsékleten. Atalálmány további tárgya eljárás a fenti keverék előállítására olymódon, hogy egy izobutilén-alapú polimert egy félig kristályoskopolimerrel összekevernek, ahol a félig kristályos polimeretiléntartalma legalább 45 tömeg% a félig kristályos kopolimerrevonatkoztatva, a kikeményített keverék légáteresztése kevesebb mint 8x 10-8[cm3-cm/cm2-sec-atm] 65 °C hőmérsékleten. ÓThe subject of the invention is a polymer mixture that contains an isobutylene-based polymer and a semi-crystalline ethylene copolymer, where the ethylene content of the semi-crystalline ethylene copolymer relative to the total weight of the semi-crystalline copolymer is at least 45% by weight and the air permeability of the cured mixture is less than 8 x 10-8 [cm3 -cm/cm2-sec-105 Pa] at a temperature of 65 °C. Another subject of the invention is a process for producing the above mixture by mixing an isobutylene-based polymer with a semi-crystalline copolymer, where the ethylene content of the semi-crystalline polymer is at least 45% by weight of the semi-crystalline copolymer, the air permeability of the cured mixture is less than 8x 10-8[cm3-cm/ cm2-sec-atm] at 65 °C.
