| Outline of Final Research Achievements |
Polypropylene (PP) oligomer was prepared by combination of photodegradation using a quasi-enzyme system [TiO2/polyethylene oxide (PEO) and of methyl linoleate (ML)]. The oligomerization yield is ca. 10%. The number average molecular weight and molecular weight distribution were ca. 2,000 and 2.3, respectively. The oligomerization of polystyrene was performed by the separation type quasi-enzyme system. The ML was painted on the PS film(thickness 0.05mm) containg 1% TiO2, and the film was photodegraded by UV irradiation for eight hours. The fractions of less than 100,000 molecular weight of the 8h-photodegraded PS film was 70%, showing that the oligomerization quickly occurred.
