Chapter 16, Problem 16.26P

Interpretation Introduction

Interpretation:

The crystalline weight percent of the given structure is to be determined.

Concept Introduction:

The formula to calculate the crystalline weight percent $\left(\%\text{ Crystalline}\right)$ of a polymer structure is:

  $\%\text{ Crystalline}=\frac{{\rho }_c}{\rho }\frac{\left(\rho -{\rho }_a\right)}{\left({\rho }_c-{\rho }_a\right)}\times 100$   ....... (1)

Here, $\rho$ is the measured density of the polymer, ${\rho }_c$ is the crystalline density of the polymer, and ${\rho }_a$ is the amorphous density of the polymer.
