Anti-static styrene polymer particles |
摘要 |
Expandable styrene polymer particles which have anti-static and anti-lumping properties during expansion and after molding into an article are produced by adding 0.1 to 0.4 parts of trialkyl alkylalkoxylated quaternary ammonium salts, per 100 parts of polymer particles by coating of the expandable polymer particles with the salts. The salts may be added as sole antistatic agent or in addition to the known internal additives which impart fast-cool and anti-lump properties.
