摘要: The present invention relates to a non-isocyanate polyurethane (NIPU) obtained from a diamine and an isosorbide bis(alkylcarbonate). The present invention also relates to an adhesive binder obtained from reacting said NIPU described herein with an acrylic monomer. The invention also relates to a method of preparation the NIPU and to a method for the preparation of the adhesive binder. Adhesive binders according to the invention may be used in wide range of adhesive formulations depending of the application of choice.

摘要: An adhesive composition comprises a polyurethane polymer, a solvent and a co-solvent, wherein the polyurethane polymer is an internally and/or externally hydrophilized thermoplastic polyurethane having a mass average molecular weight Mw, as determined by gel permeation chromatography against polystyrene standards using N,N-dimethyl acetamide as the eluent, of ≥ 50000 g/mol, the solvent is a polar-aprotic solvent such as MEK and the co-solvent is water.
The polyurethane polymer, the solvent and the co-solvent are present in such amounts that they form a dispersion.
The polyurethane polymer content is ≥ 10 weight-%, based on the total weight of the composition.-
