Abstract:

Article Preview

The chloroprene rubber (CR) and trans isoprene rubber (TPI) combined with methyl methacrylate (MMA) and α-Methylacrylic acid (MAA) to obtain a tetrabasic graft copolymer adhesive in a low poisonous mixing solvent. The effect of solvent, ratio of CR and TPI, benzoyl peroxide (BPO) amount, the dosage of MMA and MAA on the adhesive properties was investigated by studied the relationship between graft percentage (GP) and the T peel strength (T-PS) of various graft copolymer adhesives. The results showed that an excellent tetrabasic graft copolymer adhesive was obtained by a copolymerization of CR, TPI, MMA and MAA was 85 g, 15 g, 0.8 g, 60 g and 10 g using 0.8g BPO as initiator in a low poisnouos mixing solvent consisted of 124 g ethyl acetate (EA), 44 g pyroacetic spirit (PK) and 32 g toluene (TOL) at 85 °C for 5 h. The chemical structure of the tetrabasic graft copolymer adhesive was characterized by FTIR.
