MULTILAYER LAMINATE WHICH CAN BE USED AS A BARRIER LAYER OF A TYRE

摘要

The invention relates to a multilayer laminate for a tyre comprising at least two vertically adjacent layers wherein: the first layer is made of a first composition including at least 50 phe of one or more optionally substituted isobutylene and styrene copolymers; the second layer is made of a second composition including i) at least 50 phe of one or more thermoplastic elastomers including at least one first block compatible with the one or more optionally substituted isobutylene and styrene copolymers and at least one second block compatible with a diene polymer; and ii) one or more polyarylether polymers. The invention also relates to a pneumatic object including said multilayer laminate. The invention also relates to the use of the multilayer laminate as a barrier layer against inflation gases, preferably as a barrier layer of a tyre. Finally, the invention relates to a method for preparing the multilayer laminate.
