    <subfield code="a">&lt;p&gt;Ushbu maqolada tabiiy va sintetik smolalar, xususan fenol-formaldegid, melaminoformaldegid va boshqa smolalar haqida ma&amp;rsquo;lumot berilgan. Tajribalarada melaminoformaldegid smolasini butanol bilan modifikatsiya qilingan birikmasi olish va olingan mahsulotni GOST-9980,2 bo&amp;rsquo;yicha sintezlangan mahsulot bilan taqqoslanadi. Adabiyotlardan ma&amp;rsquo;lumotlar o&amp;rsquo;rganilib, tahlil qilindi va mavzu bo&amp;rsquo;yicha patentlar ko&amp;rsquo;rib chiqildi. Kimyoviy texnologiya kafedrasi laboratoriyasida melaminformaldegid smolasini n-butanol bilan modifikatsiyasini laboratoriyada sintezi amalga oshirildi. Olingan smolaning fizik-kimyoviy ko&amp;#39;rsatkichlari aniqlandi. Tajriba olingan melamin formaldegidning n-butanol bilan modifikatsiya qilingan smolaning qovushqoqligi, elektr qarshiligi, mustahkamligi, zichligi, nur sindirish burchagi, adgeziya va boshqa xususiyatlari aniqlandi. Tajriba natijasida GOST-9980,2 bo&amp;rsquo;yicha sintezlangan namunaga taqqoslandi va ijobiy natijalar olindi.&lt;/p&gt;</subfield>
