Thermosetting polymers. Polymer with cross-links. Thermosetting polymers have different properties to thermosoftening polymers. Once moulded, they do not soften when heated and they cannot be reshaped. Vulcanised rubber is a thermoset thermoset: Material that becomes permanently hard after heating. used to make tyres.Its polymer chains are joined together by cross-links, so they cannot slide past each other easily.

Best Answer: Polymers are formed from chains of longer repeating molecules (i've been told in an exam not to use the word monomer as it doesn't get you the mark). The longer the chanins the stronger the polymer. The more intermoloecurar bonding there also is makes it stronger.olymers are created by forming long repeating chains of molecules To break down a ploymer, chemical attack, and oxidation (if thats not chemical attack) are good ways to break down polymers. Heat doesn't tend to break the structure down, if its not too hot. - which sounds silly, but you get the idea, I hope.
