Polyether Polymer Matrix

A resin comprising a polymer matrix comprising a plurality of functional groups,

• wherein the polymer matrix is obtainable by aminolysis of a precursor resin with a functional amine, and
• wherein the precursor resin is obtainable by polymerisation of a well defined mixture of i) cross-link monomers comprising of two or more polymerizable groups, such as vinyl or cyclic ether compounds and ii) aminolytically sensitive monomer, comprising of one polymerizable group, such as a vinyl or a cyclic ether group, and an aminolytical sensitive group.
