IMPROVEMENTS IN OR RELATING TO PHTHALATE PLASTICISER ESTERS
摘要
The liquid volume resistivity of plasticiser esters is improved by purifying the ester with an adsorbent having a pH in the range 6 to 11. It is preferable to use a mixture of a filtration aid and an adsorbent. A plasticiser having a desirable combination of high liquid volume resistivity, low amount of light ends and low carbonyl number is obtained.
