Abstract
Derivative of epichlorohydrin of natural origin, selected from the group consisting of glycidyl ethers presenting an epoxide equivalent weight higher than or equal to 50 g/equivalent and lower than or equal to 15000 g/equivalent, of glycidyl esters, of glycidyl amides, of glycidyl imides, of glycidyl amines, and of any mixture thereof, and of which the 14C mass content is such that the ratio 14C/12C is higher than 0.7 10−12.
Claims17
A derivative of natural origin, selected from the group consisting of glycidyl ethers,
- wherein said glycidyl ethers present an epoxide equivalent weight higher than or equal to 50 g/equivalent and lower than or equal to 15000 g/equivalent, and
- wherein said derivative is obtained from epichlorohydrin of natural origin and from at least one compound containing at least one active hydrogen atom, at least one part of said compound having been obtained from renewable raw materials, the natural origin of the derivative resulting in a 14C mass content of said derivative which is such that the ratio of 14C/12C is higher than 0.7×10−12.
