Abstract

POSTUPAK ZA DEZAKTIVIRANJE RADIKALA, koji nastaju pre ili za vreme radikalne polimerizacije diena i/ili vinilaromatičnih jedinjenja i u datom slučaju drugih komonomera, naznačen time, što se reakcionoj smeši u trenutku željenog prekidanja polimerizacije dodaje dovoljna količina aromatične hidroksitiokarbonske kiseline ili njene soli opšte formule: pri čemu n,m,p,q, i r imaju vrednosti 0 ili 1, pod uslovom da zbir n+m+p mora da ima vrednost najmanje 1; R1 i R2 su isti ili različiti i predstavljaju C1-10 alkil, C2-10 alkenil ili aralkil ostatke sa najviše 15 ugljenikovih atoma; i A predstavlja vodonik, amonijak ili poželjno, jon alkalnog metala. Prijava sadrži još 5 zavisnih zahteva.
