Review :
“Thus, this is a felicitous compilation on polymer chemistry, physics and engineering, which I can recommend to any of my undergraduate students.”  (Materials Views, 31 January 2014) “With its balanced presentation of polymer chemistry, physics, and engineering applications, the updated and revised third edition of Fundamental principles of polymeric materialsprovides a solid understanding of the main concepts underlying polymeric materials.”  (RFP Rubber Fibres Plastics International, 1 January 2014) “This is certainly an excellent book from which to learn about various aspects of polymer chemistry.”  (IEEE Electrical Insulation Magazine, 1 January 2014) “Recommended.  Upper-division undergraduates and lower-level graduate students.”  (Choice,  1 December 2012)
