what is cross linking polymerization a science with bobert video short

Chemists love polymers because they can control the properties of the polymer. They do this first by first selecting the type of link or monomer in the polymer that they want to synthesize. They also modify the polymer’s properties by controlling the degree of cross-linking that occurs within the polymer. voice: Cross-linking? What’s that? Recall that a polymer consists of a range of chain lengths….. If you place several chains together in a bucket, the chains get intertwined and mixed around. This is just what happens to polymers. A polymer with no cross-linking is just like this bucket of individual chains. However, a polymer with cross-linking has its individual chains or polymer molecules pemanently linked together! This is called cross-linking. Cross-linking greatly strengthens the rigidity of the polymer. So through selection of the monomer and controlling the amount of cross-linking, chemists can choose and pick the properties of polymers they synthesize and also come up with new polymers never before created!
