I. An alternating copolymer is a copolymer comprising two species of monomeric units distributed in alternating sequence. II. A random copolymer is one in which the monomer residues are located randomly in the polymer molecule. II. Graft copolymer is a copolymer formed when the two monomers cluster together and form 'blocks' of repeating units. IV. A block copolymer is a type of copolymer in which one or more blocks of homopolymer are arafted as branches onto a main chain, meaning it is a branched copolymer with one or more side chains of a homopolymer attached to the backbone of the main chain.
