Giant molecules. 

 - Videocassette (VHS)(23 min.) : sd., b&w, 1/2 in. 
<br/><br/> We're entirely surrounded by giant molecules many of which are polymers. All living matter contains these chain-like molecules that you can find in all sorts of natural products from glass to wood to wax and rubber. This programme relates to man-made polymers. It explains how polymers are classified into the two basic types and shows how their physical properties can be understood in terms of their structure.
