The vibration welding of poly(methyl methacryalte) to itself and to polycarbonate,poly(butylelne terephthalate),and modified poly(phenylene oxide)

摘要

The weldablity of polymehtyl methacrylate)(PMMA) to itsel fand to polycarbonate (PC),poly(butylene terephthalate)(PBT),and modified poly(phenylene oxide)(M-PPO) is assessed through 120 and 250 Hz vibration welds.Weld strengths equal to those of the base resin have been demonstrated in welds of PMMA and M-PPO,respectively,have been demonstrated.PMMA does not welt well to PBT;the highest weld strength obtained was 21% of the strength of PBT resin.
