Epoxy-terminated siloxane-contained resin (BCDS/OBBA-ETS) with high tensile strength and lap shear strength as well as good thermal stability was synthesized and characterized by (1)H-NMR and Fourier transform infrared spectroscopy. Carboxy-capped disiloxane-4,4'-oxybis (benzoic acid) ester oligomer (BCDS/OBBA) was firstly prepared from the reaction between 1,3-bis(chloromethyl-1,1,3,3-tetramethyl-disiloxane and 4,4'-oxybis(benzoic acid) (OBBA) in N,N-dimethylformamide in the presence of triethylamine. Then, the BCDS/OBBA oligomer was reacted with epichlorohydrin to obtain the title BCDS/OBBA-ETS resin. Cured with liquid polyamide L-651, or diethylenetriamine, the mechanical and thermal properties as well as the lap shear strength of the BCDS/OBBA-ETS resin were evaluated. The results indicated that the BCDS/OBBA-ETS resin exhibited good thermal stability below 200 degrees C, and the glass transition temperature (T(g)) was about 64 degrees C after cured with L-651. The tensile strength of same cured BCDS/OBBA-ETS resin was 27.46 MPa with a stain at break of 42.11%, and the lap shear strength for bonding stainless steel was 18.59 MPa.
