Abstract
Изобретението се отнася до метод за получаване наполиамиди чрез полимеризация на лактами в присъствие на метални оксиди като хетерогенни катализатори. Металните оксиди се използват във форма, която позволява механичното им отделяне от реакционната смес по време или след завършване на полимеризацията.
