Abstract
Procedeu de polimerizare în suspensie a monomerilor vinilici în prezenta unui sistem de initiere constituit din cloroformiat de alchil dizolvat în monomer si apa oxigenata dizolvat în monomer si apa oxigenata dizolvata în faza apoasa, la un pH cuprins între 7 si 13, de preferinta 7 si 11, caracterizat prin aceea ca în mediul de polimerizare se introduce pentru mentinerea pH-ului alcalin o baza organica, solubila în mediul de polimerizare aleasa dintre:piridina, trietilamina, picolina hidroxi cuaternari de amoniu.
