Influence of Processing on Polymeric Materials

  • G. Marrucci
Part of the Physics of Solids and Liquids book series (PSLI)


In this chapter, the most common processes by which thermoplastic and fiber-forming polymers are formed into manufactured items are briefly surveyed. In most cases, solidification of the liquid polymer takes place when it is still flowing or when it has just stopped flowing. As a consequence of the flow, the flexible polymer molecules are stretched and oriented. The resulting items may then exhibit properties very different from those obtained when the polymer is solidified under quiescent conditions.
