Explanation: Synthetic polymers are classified on the basis of their origin and are known as man-made polymers.

Explanation: At the end of the suspension polymerization, the polymer formed appears in the form of tiny beads or pearls, so it is also known as pearl polymerization.

Explanation: Condensation polymerization can be accomplished by employing biphasic interfacial polymerization technique.

Explanation: The reaction between pthalic acid and glycerol initially results into linear or branched polymer but, due to trifunctionality of glycerol, ultimately cross-linking takes place between the molecules.

Explanation: The emulsion polymerization technique allows the increase in both the rate and degree of polymerization simultaneously by increasing the number of polymer particles, N at a fixed rate of initiation.

Explanation: Living polymerization enables the formation of block polymers by adding a fresh monomer to the reaction. It results in the production of mono-disperse polymers and can also help in generating the functional –ended polymers by reacting the living ends with different reagents.

Explanation: The measurement of initiator decomposition is done during actual polymerization, as an independent measurement in the absence of monomer would lead to errors.

Explanation: When the polymerization proceeds without a change in feed and copolymer composition, then there is an occurrence of azeotropic polymerization.

Explanation: Chain growth polymers contain only −C−C− linkages whereas step growth polymers contain atoms like O, N, S in between the −C−C− linkages.

Explanation: Syndio-tactic sequence represents alternate d and l configurations, thus shows a good tendency to crystallize.

Explanation: The medium viscosity in polymer systems is much higher than the systems of small non-polymeric molecules. Besides, there tend to become insoluble after a certain range of chain length or molecular weight.

Explanation: The functional group at a free end has a good degree of mobility to collide and faster reaction to take place.

Explanation: Styrene is capable of polymerizing by radical as well as cationic and anionic mechanisms. It is placed at a low position in each series of reactivity.

Explanation: The ratio, commonly, is used to represent the molecular size distribution, which is given by (1+p).

Explanation: Glycol is a bifunctional monomer having hydroxyl groups which will establish cross-links by combining two branches.

Explanation: Acrylonitrile contains ─CN group which is an electron withdrawing group and cannot adopt a cationic pathway. Anion, free radical and coordination complex can polymerize it to high molecular weight polymer.

Explanation: In condensation polymerization, the molecules undergo condensation reaction with a release of a byproduct molecule like water, HCl, etc.

Explanation: The initiator efficiency not only depends on initiator molecules but is also affected by condition of polymerization and the solvent used.
