Rosin maleic anhydride adduct (RMA) was prepared by Diels-Alder reaction of rosin with maleic anhydride. Methylphenylcyclotrisiloxane (D₃^Me,Ph) was synthesized from methylphenyldichlorosilane in the presence of zinc oxide catalyst, and then polymerized at 90 ℃ for 24 h to obtain amino group terminated polymethylphenylsiloxane prepolymer (APPS). Rosinamideimide was prepared from the polycondensation of RMA with APPS at 120 ℃ for 6 h in the presence of triphenylphosphite catalyst. The structure and thermal properties of the polymer were characterized by FT-IR, NMR(¹H, ¹³C, ²⁹Si), DSC, and TGA. Rosinamideimide showed good thermal stability and adhesion to aluminum metal substrate. T_g was 259 ℃, however T_m was not observed. The residual weight (W_tr) at 500 ℃ was 55%, and the adhesion strength was 1.45 MPa.
