Abstract
The invention concerns a method for preparing polymers having at least a thiol function, comprising pyrolysis of at least a polymer having at least a function of formula (I), wherein: R1, R2, R3 and R4 are such as defined in the description
Claims13
A process comprising:
- pyrolyzing at least one polymer having a single functional group comprising:
- where R1, R2, R3 and R4 are identical or different and comprise:
- a hydrogen atom, alkyl, acyl, aryl, aralkyl, alkene or an alkene radical, an aromatic, saturated or unsaturated, a cycloalkyl radical, a heterocyclalkyl radical, or a polymer chain;
- wherein the pyrolysis is carried out on the polymer having a single functional group in solution or in an emulsion;
- and
- wherein the pyrolyzing converts the functional group to a thiol functional group.
