- Discuss the suitable initiator to start an addition polymerization. Define what is auto-acceleration, what causes this effect and how to minimize this effect. Briefly discuss emulsion and suspension polymerization techniques.Network phenol-formaldehyde; linear and heavily crosslinked cis-isoprene State whether it is possible to determine whether one polymer is more likely to crystallize than the other. If it is possible, note which is the more likely and then cite reason(s) for your choice. If it is not possible to decide, state why.Sketch and label the expected stress-strain curves at room temperature for lightly cross-linked poly(butadiene) and reinforced poly(methyl methacrylate). Compare the behaviour of each specimen in terms of modulus and toughness.

Draw chemical structure of the active groups and classify them according to their polarities.Outline methods for the production of vinyl polymers using bulk methods. Bulk polymerization or mass polymerization is a facile and environmentally friendly method for formation of polymer nanocomposites due to the low viscosity of monomers. It is carried out by adding a soluble radical initiator to pure monomer in liquid state. The initiator should dissolve in the monomer. The reaction is initiated by heating or exposing to radiation.
