WebCopolymer. Different types of polymers: 1) homopolymer 2) alternating copolymer 3) random copolymer 4) block copolymer 5) graft copolymer. In polymer chemistry, a copolymer is a polymer derived from more than one species of monomer. The polymerization of monomers into copolymers is called copolymerization. WebSimilarly, block copolymers can be made of hydrophilic and hydrophobic blocks and form similar structures in water17. Such an effect can be easily expanded into any selective solvent condition and thus, as long as the block copolymers are made of soluble and insoluble blocks, they can assemble into defined architectures18.
