The crystalline poly(ethylene terephthalate) is a rather brittle material, which is characterized by relatively low values of toughness. For expanding the field of application of crystalline poly(ethylene terephthalate), it is necessary to raise its toughness considerably, retaining its high strength properties. Our study provides an effective route to prepare toughened PET blends by melt-blending with neat Vistamaxx™ Performance Polymer. Different types of Vistamaxx with different molecular weight and ethylene content were utilized to investigate the mechanical properties of PET/ Vistamaxx blend.

PET Toughness Improvement by Adding Vistamaxx™ Performance  Polymers 


The crystalline poly(ethylene terephthalate) is a rather brittle material, which is characterized by  relatively  low  values  of  toughness.  For  expanding  the  field  of  application  of  crystalline  poly(ethylene terephthalate), it is necessary to raise its toughness considerably, retaining its high  strength properties. Our study provides an effective route to prepare toughened PET blends by  melt‐blending with neat Vistamaxx™ Performance Polymer. Different types of Vistamaxx with  different  molecular  weight  and  ethylene  content  were  utilized  to  investigate  the  mechanical  properties of PET/ Vistamaxx blend. 


Polyethylene  terephthalate,  commonly  abbreviated  PET,  is  the  most  common  thermoplastic  polymer  resin  of  the  polyester  family  and  is  used  in  a  lot  of  applications  based  on  viscosity  differences.  Like  fibers  for  clothing,  containers  for  liquids  and  foods,  thermoforming  for  manufacturing and so on. PET continuously attains extensive interests because of its excellent  chemical resistance, good mechanical properties, and low cost. However, the brittleness and  notch  sensitivity  are  the  major  drawbacks  of  PET,  which  limit  its  application  in  super‐high  toughness  areas.  To  improve  the  toughness,  by  involving  polyolefin  or  rubber  is  generally  recognized to be a very effective method for thermoplastics.  

Vistamaxx™ performance polymers were introduced to market in 2004 as a propylene based  thermoplastic  elastomer.  It's  toughness,  elasticity,  softness,  sealability,  transparency  and  adhesion make it a perfect candidate in modification, compounding, adhesive and hygiene non‐ woven applications.
