A thermoplastic adhesive composition including a linear oligomer and/or a linear polymer obtained by co-oligomerisation and/or copolymerisation of a mixture including at least one monomer including two end-standing glycidyl groups and at least one monomer including two secondary amine groups, wherein the ratio of the number of end-standing glycidyl groups to the number of secondary amine groups in the mixture is between 1:1.1 and 1:2.75. Also, a liquid adhesive composition, methods for producing the thermoplastic adhesive composition, and methods for applying and removing the thermoplastic adhesive composition and the liquid adhesive composition.
A thermoplastic adhesive composition comprising a linear oligomer and/or a linear polymer obtained by co-oligomerisation and/or copolymerisation of a mixture comprising at least one monomer comprising two end-standing glycidyl groups and at least one monomer comprising two secondary amine groups or one primary amine group, characterized in that the ratio of the number of end-standing glycidyl groups to the number of amine groups in the mixture is between 1:1.1 and 1:2.75.
A method of producing a thermoplastic adhesive composition comprising a linear oligomer and/or a linear polymer, comprising reacting a mixture comprising at least one monomer comprising two end-standing glycidyl groups and at least one monomer comprising two secondary amine groups or one primary amine group, characterized in that the ratio of the number of end-standing glycidyl groups to the number of amine groups in the mixture is between 1:1.1 and 1:2.75.
