Studies have found that the rate of crosslinking of a thermoset material can be increased when both electron beam irradiation and thermal heating are used together. Explain why this is so.
 
  What will be an ideal response?

Question 2

What is the likely cause of the inability of shrink-tubing to shrink sufficiently to bind two wires tightly when it is shrunk onto a connection between the wires?
 
  What will be an ideal response?

Answer to Question 1

The thermal heating gives the molecules more movement and this movement can make the crosslinking reactions more effective and more rapid because there are more collisions between the molecules and, therefore, more reactive occurrences.

Answer to Question 2

Because its post-crosslinked pre-stretched condition is larger than what the application calls for.
