Aqueous suspension polymerization process of compositions containing styrene in the presence of rosin acid derivatives and their salts and expandable or non expandable polystyrene obtained |
| abstract |
The polymerization of compositions containing styrene by an aqueous suspension process in which is used a suspending agents system constituted by a mineral agent and, an extending agent which is at least a rosin acid derivative (abietic acid, neoabietic acid, dextropimaric acid) or their salts of a metal belonging to Group IIa of the Periodic Classification of elements. The use of this extending agent has the advantage to ameliorate the surface aspect of moulded articles obtained from expanded polymer pearls prepared with the above polymerization process. |
