Abstract
Disclosed is a method of using at least one functionalized hydroxycarboxylic acid oligomer as an adhesive for bonding materials. Also described is a process for manufacturing functionalized hydroxycarboxylic acid oligomers including at least one stage for polycondenzation of a hydroxycarboxylic acid and a functional agent, as well as functionalized hydroxycarboxylic acid oligomers that can be obtained and the adhesive compositions that include them.
Claims19
A method for bonding materials, comprising steps of:
- providing an adhesive comprising at least one functionalized hydroxycarboxylic acid oligomer that is obtained by at least one stage for polycondensation of a hydroxycarboxylic acid in the presence of a functional agent that is derived from an oil or a fat of natural origin;
- and
- suitably applying the adhesive to the materials to be bonded.
A process for manufacturing a functionalized hydroxycarboxylic acid oligomer, comprising a step of carrying out polycondensation of a hydroxycarboxylic acid in the presence of a functional agent that is derived from an oil or a fat of natural origin.
