Process for preparing expandable styrenic polymer particles |
| abstract |
Process for the production of expandable particles of styrene polymers, having improved processability characteristics, which comprises: i) producing expandable particles of styrene polymers containing from 2 to 20% of an expanding agent incorporated; ii) covering these particles with an antistatic agent in a quantity of less than 1% by weight; iii) vigorously frictioning the particles in a mixing apparatus in order to heat their surface, in a short time, by simple mechanical friction; iv) discharging the particles thus treated from the mixing apparatus. |
