Chemistry

5. When termination is by chain transfer, what is therelationship of average degree of
polymerization DP) and the kinetic chain length? Compare andcontrast dendrimers with
block copolymer micelles, globular proteins, inorganicnanoparticles in terms of attributes and
hkely utlity in the following applications:(a) drug delivery;(b) homogenous catalysis, and(c)
solubilization.


6. When a dilute solution of block copolymers undergoesmicellization, ie, some numbers
of
chains aggregate into a(usually spherical) assembly to shieldone block from the solvent it does
not lke, the light scattering intensity increases. In fact, ifmicellization is induced by changing
temperature at a fixed conlentration the ratio of theintensity after micellization to that before
micellization is a good estimate of the average aggregationnumber of the micelles. Explain this
observation.+

Degree of polymerisation is given by DP 11P Kinetic chain length is given by the propagation step which will be divided by initiation step But when the reaction goes towards completion the concentration of monomer become equal to zero and then the kinetic chain length is equal to the number average degree of polymerization of the polymer That means kinetic chain length is an average quantity Dendrimers are    See Answer
