Chapter 1. Introduction to Polymer Science
Polymer comes from life
From Caouchouc (“weeping tree”) to vulcanized rubber
Charles Goodyear (1800-1860)
Vulcanization of natural rubber
HERMANN STAUDINGER (1881-1965)
1953 Nobel Laureate in Chemistry for his discoveries in the field of macromolecular chemistry. Background Residence: Germany
Macromolecular Hypothesis
1.1 From little molecules to big molecules
Alkane/Polyethylene
Monomer oligomer polymer
Molecular weight-melting temperature relationship for the alkane series
Tm of PE
Comparison of wax and polyethylene structure and morphology
Entanglement of polymer chains
Low molecular weightNo entanglement
High molecular weightChains are entangled
1.2 Molecular weight and molecular weight distributions
1.2.1 Effect on tensile strength
b is tenile stress to breakMn is the number-average molecular weightA and B are constants
1.2.2 Molecular weight average
