SHOCK-RESISTANT MODIFIED POLYETHER SHOWING LOW GAS PERMEABILITY HAVING CONSTANT SIZES AT INCREASED TEMPERATURE

摘要

FIELD: polymeric materials. SUBSTANCE: shock-resistant modifying agents were dissolved in melted polyether in order to obtain eutectic alloy. During slow cooling this allow freezing forms mixture of particles of shock-resistant modifying agent included in polyether matrix. It is possible to control the size and deposit distribution from the melt and regulate mechanical properties. Precipitation can be controlled at homogeneous or heterogeneous nucleation by either addition of nucleation agent or surface addition that is suitable for nucleation. Invention provides the process of making the indicated polyether, article containing this polyether and manufacture process of this article. Crystalline polyether article can be used as container for foodstuffs for microwaves and usual furnaces and/or the frozen foodstuffs, it exhibits improved property of gas barrier, impact strength and size stability after pressing at the range from -60 C to 200 C. EFFECT: enhanced quality during heating.
