SUSPENSION POLYMERIZATION OF STYRENE IN A GEL MEDIUM

In this study, a method for the suspension polymerization of styrene in a dispersive gel medium was developed. An aqueous solution of methylcellulose was used as the gel. The dependence of the dynamic viscosity of methylcellulose solutions on temperature was established. The polymerization of styrene was carried out during 2 or 4 hours at a temperature of 60-80 ° C at the gelation point of methylcellulose solu-tions. The ratio of styrene to methylcellulose was 1:10. When the pol-ymer was cooled, solid polymer particles precipitated on the bottom of the vessel and could be easily separated. The particle polymer sizes var-ied from 0.01 to 7 m
