Structure Development During Polymer Processing

30 Years Ago, Polymer Processing Was Considered To Be A Set Of Operations Aiming At Imparting A Desired Shape To The Material, While Its Final Properties Were Defined Exclu Sively By The Molecular Structure And Architecture Resulted From The Respective Synthetic Approaches. These Two Fields Of Knowledge - Polymer Processing And Polymer Structure - Grew Closer As Several Scientific And Technological Works Disclosed The Microstructure And Other Morphological Features Developed By Polymeric Systems Upon Different Process Ing Conditions. Even Before The Real Understanding Of The Polymer Structural Details, Engineers Were Able To Make Use Of The Effect Of Molecular Orientation And To Manufacture Polymeric Fi Bres With Enhanced Properties In Terms Of Stiffness And Strength.
