• where R is derived from an aliphatic diamine, an aromatic diamine, a diaminosiloxane or a polyether diamine;
• where Ep has a structure as shown in formula (2);
• where (A)n is obtained from an aromatic epoxy resin containing structure selected from the group consisting of formula (3) and formula (4);
• or obtained from a aliphatic epoxy resin containing structure selected from the group consisting of formula (5), formula (6), formula (7), formula (8) and their combinations;
• where R1 is independent of one another, and comprises the cyclic hydrocarbon with carbon number 1 to 5;
• polyphenols with carbon number 6 to 10;
• linear hydrocarbons or halogen substituted hydrocarbons with carbon number 1 to 20;
• carbonyl, imine, amide, phosphoryl, phosphonate, phosphine, carbonyl, carboxyl, silyl, ether, thioether, sulfonyl, selenoether, ketone, aldehyde or ester;
• where R2 is independent of one another, and comprises hydrogen, halogen, alkyl, alkenyl, alkynyl, hydrocarbyl, hydroxyl, amino, a nitro, or alkoxyl with carbon number 1 to 5;
• where Z and n are independently integral numbers between 1 to 5;
