answer 1-4
Polymers are large molecules that exist in chains composed of smaller repeating units called monomers. They can come in many forms according to substitution patterns and functional groups. Linear polymers have the monomers repeated in just one line. Cross-linked polymers are branched. Linear polymers have just two ends. Cross-linked have more than two ends. If more than two functional groups (reactive sites) are present in the monomer, the monomers may connect to each other by cross-linking to form...
