Методами механической релаксации напряжений в инертной и озонсодержащей атмосфере и электронного парамагнитного резонанса исследована озоностойкость, фазовый состав и структура межфазных переходных слоев вулканизированных смесей бутадиен-нитрильных каучуков (БНК) с поли (винилхлоридом) (ПВХ). Образцы были получены из БНК марок СКН-18, СКН-26, СКН-40 и ПВХ (полученный эмульсионной или суспензионной полимеризацией) методами высоко- и низкотемпературного смешивания с последующей обработкой в термостате. Механизм озонозащитного действия термопласта (ПВХ) в смеси с БНК рассматривается для систем, обладающих различной степенью однородности.
