abstract = {In this work, various loads of nanomaterials and aliphatic dendritic polymerswere mixed with fibre grade
PET (Polyethylene terephthalate) to study its dye ability, thermal and thermal-mechanical properties.
A twin screw extruder equipped with sheet (profile) die was used for mixing the compounds. Thermal
behaviour of the neat PET and the compounded sheet samples were studied using differential scanning
calorimeter and dynamic mechanical thermal analysis. It was observed that the T_g of samples decreased
gradually by increasing the load of Boltorn H40 as a nanomaterial additive while the T_m remained almost
the same. The difference between the glass transition temperature for neat PET and the compounded
sample including 3% additive was about seven degrees. In spite of the decline in T_g, the moduli of
samples containing additive increased as revealed by DMTA analysis. The presence of this dendritic
polymer in compounded PET acted as a cross linking or antiplastisizing agent and made the fibre grade
PET compounds more compact than pure PET. So the disperse dye molecules neither were able to stay
between the molecules of compounded PET nor were able to trap between the dendritic branches.},
