Disclosed is a process for preparing a polyester or copolymer containing ester functionalities. The process can comprise: wherein

Process for preparing a polyester

The present invention relates to a process for the preparation of a conductive polymer composition comprising the steps of A) providing a latex containing a conductive polymer; B) mixing the latex from A with either an aqueous latex of a polymer, or with (a) water-soluble precursor(s) of a polymer; C) removing water from the so obtained mixture; D) heating the product from step C) to a temperature at which the polymer added in step B flows or where the polymer introduced in step B is formed from out of its precursor(s); and E) processing and/or solidifying the product of step D) into a desired form, wherein the amount of conductive polymer is between 0.1 and 10 wt % relative to the total of the total of components in step A and B. In step A optionally carbon nanotubes (CNTs) in an aqueous medium are preferably added to the latex containing conductive polymer. In that case the conductive polymer may behave as a conductive polymeric surfactant for the CNTs dispersed in water.

Process for the preparation of a conductive polymer composition

The invention relates to polycarbonate containing a dianhydrohexitol residue, obtainable from a polysaccharide, and a polyol residue, wherein the polycarbonate comprises between 0.2 and 5 mmol hydroxyl groups per gram polymer. The polycarbonate may be branched and comprises functional groups that can react with suitable crosslinkers. The polycarbonate can be used in for example coating compositions. 

Polycarbonate and process for producing the same

The present invention relates to a (process for preparation of a) carbon nanotubes reinforced polymer, wherein the matrix polymer has both a low molecular weight fraction as well as a high molecular weight fraction, as a result of which the level of conductivity of the resulting composite can be controlled.
