- a) Calculate the degree of Polymerization when an average molecular weight of a Polymer is 23040g/mol, having monomer of C8H8O4.arrow_forwardWhen answering the following questions , ensure that you explain in terms of both the microscopic and macroscopic structure of the materials. A) polymer - explain the difference in structure between a thermoplastic and thermoset material and explain how the structure accounts for the key generic properties of those polymers. B) composite material - for a particular composite and a fibre reinforce composite , explain the difference in structure and whst structual features dictate the properties of the material.arrow_forwardFor a given polymer, the activation energy for stress relaxation was measured to be 10 kJ/mol. If the stress relaxation time for this polymer at room temperature is 3,600 s, what would be the relaxation time at 100 ◦C?arrow_forward

As temperature is reduced, necking behavior of plastic tensile bars completely disappears b. Semi-crystalline polymers are heat treated to increase crystallinity and improve strength c. Heat treatment always results in enhanced polymer strength, modulus, and brittleness d. Strain softening happens in elastomers where the deformation gradually leads to a decrease in stiffness under constant strain rate e.
