The present invention refers to a polyesterpolyol which is obtained by reaction of at least one diol with at least one primary hydroxy group and at least one secondary hydroxy group with a saturated aliphatic dicarboxylic acid comprising a carbon chain of at least 12 carbon atoms. The invention further relates to an adhesive composition containing the polyesterpolyol, in particular a polyurethane adhesive composition.

Crystalline polyesterpolyol

The present invention relates to a hot-melt adhesive composition comprising at least one polyester polyol based on Betulin and at least one NCO-terminated compound as well as a method for the production of a laminated article using the inventive hot-melt adhesive composition.

Hot-melt adhesive composition comprising bio-based polyester polyols

The present invention pertains to reactive (moisture curing) plasticizers; adhesives and sealants containing the plasticizers and methods of bonding and sealing substrates with adhesives and sealants containing the plasticizers.

Bio-based reactive plasticizer and adhesives and sealants containing them

The present invention relates to adhesives which contain a polyester polyol on the basis of furandicarboxylic acid obtained from renewable raw materials, and to a method for bonding substrates, in particular film-like substrates, using said adhesive.

Polyester polyol-based adhesives on the basis of furandicarboxylic acid obtained from renewable raw materials

The present invention relates to amorphous polyesters on the basis of betulin, a method for producing them and their use.

Amorphous polyesters on the basis of betulin

The present invention relates to a semi-crystalline mixture of polyester polyols which recrystallises upon melting and which can be obtained by polycondensing a reaction mixture comprising one or more dicarboxylic acids selected from saturated aliphatic dicarboxylic acids having an even number of at least 8 methylene groups, and one or more diols selected from aliphatic diols which have at least one ether function. The invention also relates to a polymeric material which is obtained from the chemical modification of the mixture of polyester polyols with organic compounds which contain at least one isocyonate group and/or epoxide group. The mixtures and materials according to the invention are characterised by relatively low melting enthalpies, while the melting temperature can be set in a range of &#x2212;30 to 60&#xb0; C., meaning that it is possible to obtain easily fusible formulations containing the mixtures and materials according to the invention. The mixtures and materials according to the invention also provide such formulations with a high elasticity and breaking resistance. The present invention therefore includes the use of the polyester polyols and polymeric materials according to the invention as deforming, fusing, and extrusion means in thermoplastic materials, and the use thereof for producing adhesives and sealants, in particular hot-melt adhesives and reactive adhesives.
