Initiator mixtures, compositions, applications, methods for preparing polyol polymers and polyol polymers prepared therefrom

摘要

The present invention relates to a mixture of initiators, a composition, their use, a process for preparing a polyol polymer and a polyol polymer obtained by the process. The initiator mixture comprises: a first peroxide of formula (I) R1-OO-R2, wherein R1 and R2 independently represent an alkyl group or an alkanoyl group comprising 1 to 30 carbon atoms, preferably 3 to 20 carbon atoms, carbon, and more preferably 4 to 20 carbon atoms; and a second peroxide of formula (II) R3-OO-R4-OO-R5, wherein R3 and R5 independently represent an alkyl group having 1 to 30 carbon atoms, preferably 3 to 20 carbon atoms and more preferably 5 to 10 carbon atoms, and R4 represents a cycloalkylene group comprising 3 to 30 carbon atoms, preferably 4 to 20 carbon atoms, and more preferably 5 to 10 carbon atoms.
