The crystallization of a polymer can only proceed in a temperature range limited to glass transition temperature (\(T_g\)) on the lower side, and the equilibrium melting point (\(T_m^0\)) on the higher side. Around \(T_g\), the mobility of the polymer chains is lower, while in the proximity of \(T_m^0\), crystal nucleation is inhibited.
In a miscible polymer blend with only one component being crystalline, which option(s) correctly match(es) the Temperature conditions with Events?
In a set of copolymerization reactions, the following monomer reactivity ratios (\(r_1\) and \(r_2\)) were found for different cases.
Which option(s) correctly identify/identifies the type of copolymerization corresponding to each Case?
Which option(s) correctly match(es) the Class of additives used during polymer compounding with the corresponding Chemicals?
Which option(s) correctly match(es) the Polymer property with its appropriate Units?
During material testing, stress is applied from time \(t_i\) to \(t_f\) as shown below:
Choose the option(s) where the strain response is correctly mapped to its material class.
