| 摘要 |
The invention relates to a polymerization process wherein at least one initiator is selected from trioxepan compounds of formula Iwith R<1-3 >being independently selected from substituted or unsubstituted hydrocarbyl groups. Preferably, R<1 >and R<3 >are selected from lower alkyl groups, such as methyl, ethyl, and isopropyl, while R<2 >is preferably selected from methyl, ethyl, isopropyl, isobutyl, amyl, isoamyl, cyclohexyl, CH3C(O)CH2-, C2H5OC(O)CH2-, HOC(CH3)2CH2-, and
