Anti-static styrene polymer particles by impregnation |
摘要 |
Expandable styrene polymer particles which have anti-static and anti-lumping properties during expansion are produced by adding 0.1 to 0.4 parts of alkyl and alkylaryl ethers of polyethoxyethanol mono- and diesters of phosphoric acid per 100 parts of polymer particles during impregnation of the polymer particles with blowing agents. The esters may be added as sole antistatic agent or in addition to the known internal additives which impart fast-cool and antilump properties.
