From the structure of a segment of the copolymer , Saran, the two monomers which copolymerize to give it are to be identified. Concept introduction: A copolymer is a large molecule built by repetitive bonding of many simpler molecules called as monomers arranged alternatively. By identifying the repetitive units in the polymer the monomers that give the copolymer can be identified. To identify: From the structure of a segment of the copolymer, Saran, the two monomers which copolymerize to give it.

Question

7. When asymmetric alkenes polymerize (such as chloroethene to produce PVC), the pendant group like chlorine can be arranged in different ways. An arrangement in which the -Cl groups are arranged on the same side of the polymer chain is called a(n) , a. Atactic b. Isotactic arrangement. c. Syndiotactic d. Sporadic 8. Kevlar is a type of polymer which has a great resistance to tear. Its application includes its use in making bulletproof vests and radial tires. The two monomers used to make Kevlar are the following: H H H-O- c-0-H H-N- -N-H Monomer One Monomer Two When these two monomers join a. A molecule of CO2 will be eliminated and an ester linkage will form b. Nothing will be eliminated and the two monomers will be linked through a hydrogen to hydrogen bond c. A water molecule will be eliminated and a peptide linkage will be formed d. Nothing will be eliminated. The two monomers will be linked by a carbon-carbon bond.

Answer 1

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
