PROCESS FOR SYNTHESIS OF A COPOLYMER IN AQUEOUS DISPERSION

PROCESS FOR SYNTHESIS OF A COPOLYMER IN AQUEOUS DISPERSION

The invention relates to a synthesis process for a copolymer applied as matrix for sensor type systems. According to the invention, in a first stage, the process consists in dispersing in water 3,9-divinyl-2,4,8,10-tetra-oxaspiro[5.5]undecane in presence of sodium dodecylbenzenesulphonate as surface...

description The invention relates to a synthesis process for a copolymer applied as matrix for sensor type systems. According to the invention, in a first stage, the process consists in dispersing in water 3,9-divinyl-2,4,8,10-tetra-oxaspiro[5.5]undecane in presence of sodium dodecylbenzenesulphonate as surface-active agent with stirring at 70°C, afterwards, in the second stage there is added radical azoisobutyronitrile as initiator, dispersed in water with 2-hydroxyethyl methacrylate, or 2-hydroxyethyl methacrylate in admixture with glycidyl methacrylate, conducting the co-polymerization reaction for 6 h afterwards the resulting product is processed and lyophilized there being obtained a copolymer having an equilibrium swelling degree of 69.5%, a poly-dispersion index of 0.403 and an electric conductivity of 0.700 mS/cm.
