Abstract
The present invention provides compounds that include a fluorinated allyl xanthate group of formula (I). The invention also relates to a process for making these compounds and the use of said compounds as chain transfer agents or as monomers. The invention relates also to polymers, including copolymers, comprising units deriving from compounds of formula (I).
Claims21
A compound (AX) of formula (I):
- wherein Ra is a (per)fluorinated allyl group and Rb is a straight or branched alkyl group.
A polymer (P) comprising recurring units deriving from compound (AX) of formula (I)
- wherein Ra is a (per)fluorinated allyl group and Rb is a straight or branched alkyl group.
A polymer (Pox) of formula (VII):
- Wherein:
- w is either 0 or 1, Q is an integer between 1 and 4;
- X′ is selected among halogens, or is —O−M′+, wherein M′+ is a cation selected among H+, NH4+, K+, Li+, Na+, or mixtures thereof, n and p are, independently from each other, integers greater than 0;
- m is equal to greater than 0;
- m, n and p denoting the molar fraction of each monomer in the polymer.
