Studies on tributyl tin methacrylate (TBTM). VI. Thermal and tensile behavior of copolymer of tri‐n‐butyl tin methacrylate and methyl methacrylate

Abstract

AbstractThe thermal and tensile properties of polytributyl tin methacrylate (PTBTM) and n‐tributyl tin methacrylate–methyl methacrylate (TBTM—MMA) copolymers have been studied. Thermogravimetric study showed that with increasing the TBTM content in the copolymer the thermal stability decreases. The glass transition temperature (Tg) decreases continuously as the TBTM content increases. All the polymers showed multistep decomposition. MS study showed that in addition to monomer formation several other side reactions also take place during degradation, leading to formation of other products. Studies on tensile properties show that the tensile strength decreases with increasing TBTM content, whereas elongation at break increases. © 1992 John Wiley & Sons, Inc.
