Synthesis, chemical interaction between components, reactive grafting, and compatibilization. An attempt was made to combine the best properties of both materials (polyurethane and polycyanurate) in their semi-IPNs. The possibility of chemical interaction between the components in polyurethane/poly-cyanurate semi-IPNs leading to the formation of chemically grafted semi-IPNs was first reported by Fainleib and co-authors [34], and then confirmed in later works [35-38]. 

Polyurethane/polycyanurate grafted semi-IPNs were prepared by polycyclotrimerization of dicyanate ester of bisphenol A (DCEBA) in the immediate presence of TPU, as described in Section 3.1. During semi-IPN synthesis, at 

The chemistry of the processes occurred in the above system was studied by FTIR and matrix-assisted laser desorption ionization technique with time of flight detection (MALDI-TOF). On the basis of the results obtained, a scheme of the simultaneous and sequential reactions with formation of BP, BPT, and some intermediate and additional products, including possible substituted cyanurate, isocyanurate, and mixed triazine cycles was proposed [63].
