Van der Waals Forces

Why do the alkanes get stiffer as the molecules get longer until eventually

becoming a solid The molecules are held together by weak electrical

imbalances in adjacent molecules (caused by electron distribution)

These forces are too weak to hold short molecules together but when there

are hundreds of Carbon atoms in the chains the Van der Waal molecular

forces increase

In thermoplastics materials these molecules are

attracted to each other by relatively weak van der

Waals forces whilst in thermosetting plastics they

are joined to each other by strong permanent

covalent

bonds

2021 Melting points of polymers

2022 Glass transition temperature

203 Mechanical properties (Higgins 203)

EMMAT101A Engineering Materials and Processes

(i) Low elastic modulus low yield stress eg PVA and PTFE

(ii) High elastic modulus low elongation eg PF PMMA and PS

(iii) Low elastic modulus low yield stress but high elongation and high

stress at break eg PE and plasticised PVC

203 Mechanical properties (Higgins 203)

EMMAT101A Engineering Materials and Processes

(iv) High elastic modulus high yield stress high tensile strength

and low elongation eg rigid PVC and modified PS

(v) High elastic modulus high yield stress high tensile strength

and high elongation eg nylons and polycarbonates

Higgins

(vi) Very low elastic

modulus low yield

stress and low

tensile strength but

very high elastic

elongation eg

natural rubber and

203 Mechanical properties (Higgins 203)

EMMAT101A Engineering Materials and Processes

1 Bond bending of the carbon-carbon covalent bonds in the polymer

chain - this is manifested as the ordinary elasticity and is an

instantaneous deformation

2 Uncoiling of the polymer chains - this gives rise to high elasticity

and is very time dependent

3 Slipping of polymer chains past each other - this produces

irreversible plastic flow and is also very time dependent
