The catalase activity of the compounds with phthalate and terephthalate ligands has been studied, the former being less active than the latter. What is step growth polymerisation ? Global top five players hold a share about 10%. As can be seen from these figures, major plasticisers are high volume commodity chemicals, which take decades and billions of Euros to achieve full commercial development. The flexible plastic feel of the rubber duck may be the result of using phthalates in the manufacturing process. Dibutyl phthalate levels in rooms recently covered with polyvinyl chloride tiles ranged from 15,000 to 26,000 ng/m 3. II.
