1. The problem statement, all variables and given/known data Hello everyone, I have a couple of question regarding polymers that I some trouble understanding and hoping you guys would point me into the right direction. For ''Thermosetting'' polymers I know that they become permanently hard with covalent bonds which they chain together to resist vibration at high temperature. So is it impossible to melt this polymer? Is it true that they do not have a melting point even at extremely high temperature? Another problem I have regard polymer is about the Elastomer, why must it be cross-linked? Does it have to do with their elastic properties? I know that by cross-linking, the polymers do become stronger so cross-linking elastomers purely making them stronger? Have a nice day everyone.
