Abstract
The invention relates to a polymerization process wherein at least one initiator is selected from trioxepan compounds of formula I with R1-3 being independently selected from substituted or unsubstituted hydrocarbyl groups. Preferably, R1 and R3 are selected from lower alkyl groups, such as methyl, ethyl, and isopropyl, while R2 is preferably selected from methyl, ethyl, isopropyl, isobutyl, amyl, isoamyl, cyclohexyl, CH3C(O)CH2—, C2H5OC(O)CH2—, HOC(CH3)2CH2—, and
Claims7
A process wherein one or more monomers are polymerised using at least one initiator selected from trioxepane compounds of formula I
- with R1-3 being independently selected from hydrogen and substituted or unsubstituted hydrocarbyl groups, while two of the groups R1-3 optionally are linked to form a ring structure.
