Reactions of MacromoleculesReactions are often carried out on macromolecules in order to elucidate their chemical structure.一瞥 发表于 2025-3-23 16:43:29
Raw MaterialsPolymers may occur naturally as biopolymers or may be produced synthetically. The main biopolymer classes are polyprenes, nucleic acids, proteins, polysaccharides, and lignins. Biopolymers are skeletal or support materials, messengers, transport media, and storage reserve materials, or are just simply products of metabolism.节约 发表于 2025-3-23 20:09:25
Carbon-Nitrogen ChainsIn organic chemistry, compounds of the type RCH=NH are known as imines. Accordingly, . are polymers with the monomeric unit ?(—NH—CHR—). These kinds of polymers can be produced by polymerization of nitriles and then hydrogenating the polynitriles formed:microscopic 发表于 2025-3-23 22:20:51

Polymerization Equilibria, the position of the equilibrium is independent of the path taken to attain it. The equilibrium position may be reached via polymerization or depolymerization and the mechanism involved may be ionic or free radical.Crater 发表于 2025-3-24 19:15:20
