Thermal conductivity will increase with degree of vitrification. The glass phase has a higher conductivity than the pores that it has filled. Excerpts from this work may be reproduced by instructors for distribution on a not-for-profit basis for testing or instructional purposes only to students enrolled in courses for which the textbook has been adopted.

If the values are not the same then the other kinetic relationships need to be explored. Thus, the three equations are 1.54 = 10K3 23.24 = 150K3 95.37 = 620K3 In all three instances the value of K3 is about equal to 0.154, which means the oxidation rate obeys a linear expression.

Finally, to determine the fraction of sites that are crosslinked, we just divide the actual crosslinked sulfur/isoprene ratio by the completely crosslinked ratio.

The repeat unit for nylon 6,6 is shown inTable 14.3, from which the value ofA may be determined as follows:A = 12(C) + 22(H) + 2(O) + 2(N) = 12(12.01 g/mol) + 22(1.008 g/mol) + 2(16.00 g/mol) + 2(14.01 g/mol) = 226.32 g/molFinally, solving for n fromEquation 3.5 leads to ρCNExcerpts from this work may be reproduced by instr

This gives a molecular weight for the combined repeat unit of m(acrylonitrile-butadiene) = 3(AC) + 3(AH) + AN + 4(AC) + 6(AH) = 7(12.01 g/mol) + 9(1.008 g/mol) + 14.007 g/mol = 107.15 g/mol Or, in one mole of this combined repeat unit, there are 107.15 g. Furthermore, for complete crosslinking 4.0 mol of sulfur is required, which amounts to (4.0 mol)(32.06 g/mol) = 128.24 g.

C / mol) m2 - sThe units ofR inEquation 17.23 are length/time, or in theI scheme, m/s.In order to convert the above expression to the units of m/s it is necessary to multiply r by the atomic weightA and divide by the density ρ as rA (mol / m2 - s)(g / mol) = = m/s ρ g / m3Thus, theK'AiR =Fρ in which

To solve the (b) part of the problem we utilize the diamond-shaped cursor that is located at the top of the line on this plot. Click-and-drag this cursor down the line to the point at which the entry under the “Temperature (T):” label reads “1573”. The value of the diffusion coefficient at this temperature is given under the label “Diff Coeff (D):”. For our problem, this value is 1.2 x 10-14 m2/s.
