11.   The curves for each molar mass of the same polymer should all intersect at.

12.   Here V is the molar volume of the repeat unit whose molar mass is M o and p is the polymer density.

13.   Many of the distinctive properties of polymers are a consequence of the long chain lengths, which are reflected in the large molar masses of these substances.

14.   In this book the quantity molar mass is used and appropriate SI units are given.

15.   Because chemical methods are rather limited, the most widely used techniques for measuring the molar mass of a polymer are physical.

16.   It is still necessary to estimate the molar mass of each fraction before the MMD curve can be constructed.

17.   By assuming in dilute solutions the molar mass can be obtained from the Mark-Houwink relation.

18.   Molar mass can also alter T m.

19.   Variations in shape are found for different molar masses and when the sample is crosslinked or partly crystalline.

20.   The application of a force to a simple liquid of low molar mass is relieved by the flow of molecules past one another into new positions in the system.
