MTL 200 Final Exam | Questions & Answers ACTUAL EXAM (2025)
100%VERIFIED | QUESTIONS AND ANSWERS | GRADED A+.
Anisotropy - ✔✔directionality of properties
Bi-, trifunctional - ✔✔means that the polymer has two or three bonds
in the
structure
Branched polymer - ✔✔secondary polymer chains linked to a primary
back bone
resulted from main chain side reaction occur durinf synthesis
C = C is a ... - ✔✔rotationally rigid structure because of its double
bond it does not rotate
Ceramic Density Formula - ✔✔
Compare the sizes of anions and cations - ✔✔Anions(+) are much
larger than cations(-).
Coordination # of Tetrahedral and Octahedral Position - ✔✔1.
Tetrahedral Position - 4
,2. Octahedral Position - 6
Copolymers - ✔✔composed of 2 repeat units
Copolymers - ✔✔two or more different repeat units.
Corrosion occurs naturally in 2 ways: - ✔✔1. Oxidation (loose
electrons)
M-> M n+ +ne-
2. Reduction (gain electrons)
2H+ +2e- -> H2
crosslinked polymer - ✔✔adjacent linear chains are joined one to
another at various positions by COVALENT BONDS
Define a composite. - ✔✔any multiphase mater that is made up of 2
or more different substances (constituent phases) to create NEW
material with better properties.
Explain Non-crystalline (glass) deformations. - ✔✔- not dislocation
motion but VISCOUS flow (flows slowly due to forces)
, - atoms & ions slide past by breaking & reforming bonds.
formula for degree of polymerization for copolymers - ✔✔m= Σfi mi
Formula for length of polymer - degree of polymerization: - ✔✔DP =
Mn/ m
Mn is the number-average molecular weight.
Formula for Number- average molecular weight. - ✔✔Mn = Σxi Mi
uses statistical mean
(max on graph)
Formula for weight- average molecular weight. - ✔✔Mw = Σwi Mi
uses average weight
Functionality - ✔✔the number of bonds that a monomer can form
Homopolymer - ✔✔the repeating units are of the same type.
