MONOMERNO

MONOMERNO (az mono… va yun. nifiros-qism), moddahoi khurdmolekula, ki molekulahoyashon qodirand bo hamdigar yo molekulahoi moddahoi digar payvast shuda, dar jarayoni polimerizasiya (reaksiyahoe, ki dar natijai onho az du yo yakchand molekulai yak modda yak payvaste, ki vazni molekulaash ziyod ast, vale tarkibash az moddai avvala farq namekunad, hosil meshavad) va polikoidensasiya (reaksiyahoe, ki hangomi jarayoni onho mahsuloti ilovagi hosil megardad) polimer khosil mekunand. Aksari Monomorhoe, ki dar polimerizasiya ishtirok mekunand ba yake az du guruhi zerin mansuband: 1) ba guruhi payvasthoe, ki dar natijai kushoda shudani bandhoi karatii S®S, OS, S=0, C“N polimerizasiya meshavand (olefinho, karbogidridhoi qatori diyoni va asetileni, aldegidho, nitrilho va g.); 2) payvasthoe, ki dar natijai kushoda shudani guruhi bandhoi halqagi (mas., laktamho, laktonho, oksidi olefinho) polimerizasiya meshavand. Dar polikondensasiya hamaguna payvasthoe, ki dar molekulahoyashon du va az on ziyod guruhi reaksiyaparvar (guruhi funksionali) dorand (mas., diaminho, kislotahoi dikarbonat, aminokislotaho, spirthoi duatoma va g.), ba sifati Monomorho ishtirok karda metavonand.
