| 摘要 |
The invention concerns the use in a stabilizing composition for halogenated polymers, of at least a silylated compound of formula: (R1)4-x-Si[O-C(R2)=CH2-C(-O)(R3)]x, wherein R1, identical or different, represent an aliphatic or aromatic radical; said radicals being selected such that the silylated compound has a boiling point higher than at least 30° C. relative to the working temperature of said polymer; R3 represents an aliphatic radical R or a radical -OR1; R2, R and R1, identical or different, represent an aliphatic radical, linear or not, comprising 1 to 10 carbon atoms, or an aromatic radical, preferably comprising 6 carbon atoms, optionally substituted by at least an aliphatic radical comprising 1 to 10 carbon atoms; x is equal to 1 or 2.
