- Which of the following statement/s is/are true for co-polymers? 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. III. 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 grafted 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. iz. A Il and IV B III and IV I and II D I and IIDetermine which one would have higher crystallinity, and also briefly explain why.

- 1. Answer the following questions: (a) Why is free radical polymerization more commonly used today than ionic polymerization? (b) Almost all substituted ethylene monomers of commercial importance have the structure of CH2 = CHR or CH2 = CRR’ (where R or R' represent identical or different substituent groups). Why? (c) What are some methods for the production of conductive polymers? Give a few examples.An alternating copolymer is known to have a number-average molecular weight of 100,000 g/mol and a degree of polymerization of 2210. If one of the repeat units is ethylene, which of styrene, propylene, tetrafluoroethylene, and vinyl chloride is the other repeat unit? Why?Which of the statement/s below is/are inaccurate? a. Crosslinked polymers are stronger and have lower elongation at break than branched and network polymers O b. Geometrical isomers include syndiotactic, atactic and isotactic types and only differ by their spatial repetition of side group positions. O c. Elastomers typically have higher elongation at break values than brittle and plastic polymers and they don't experience necking which plastic polymers do experience O d. The presence of bulky side groups and double bonds decreases the freedom of the polymer chain to rotate and change it's spatial configuration The higher the percent crystallinity the higher the strength and density, and the lower the permeability of the polymer e.
