Abstract: 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 ?30 to 60° C., meaning that it is possible to obtain easily fusible formulations containing the mixtures and materials according to the invention.
