Ushbu ishda chiqindi ko‘pirtirilgan polistiroldan (EPS) ikkilamchi polimer xomashyosi olish va uning termik xususiyatlarini tadqiq etish masalalari ko‘rib chiqilgan. Chiqindi polistirol saralash, tozalash va eritish–cho‘ktirish usuli orqali qayta tayyorlangan. Dastlabki va qayta tayyorlangan polistirol namunalarining termik xususiyatlari differensial skanerlovchi kalorimetriya (DSC) hamda termogravimetrik tahlil (TGA) usullari yordamida qiyosiy baholangan. Shishalanish harorati, termik parchalanish boshlanishi va maksimal parchalanish tezligiga mos harorat ko‘rsatkichlari aniqlangan. Olingan natijalar qayta tayyorlangan polistirolning ikkilamchi polimer xomashyosi sifatida keyingi qayta ishlash jarayonlarida qo‘llash imkoniyatini baholashga xizmat qiladi.
