Why are tears in some plastics hard to start but easy to grow?
Take a generic bag of crisps, or a pack of ice cream: it takes some effort to tear open, you may want to use scissors, but then once you've opened it it's torn so effortlessly that you have to be careful to not tear it so much the contents fall…

Flory-Huggins Chemical Potential of Mixing
Within FH theory, for a binary polymer blend the following is commonly found:
$$
\mu - \mu_0 = \left(\frac{\partial A_{mix}}{\partial n_A}\right)_{V, T, n_b} =\frac{\partial}{\partial n_a}\left(\chi \phi_a \phi_b + \frac{\phi_a}{N_a}\ln(\phi_a)\…

How does contraction of polyethylene strip depend upon the heat it receives?
Strip is made of polyethylene and is cold drawn so that all polymer chains are oriented in one direction. Now, if heat is supplied to it via external source then how much will this strip contract. Is there a general formula or any article which…

What do people mean with "per unit volume" in polymer solutions theory?
I am reading Modern Theory of Polymer Solutions by Hiromi Yamakawa and in the context of the virial expansion the following puzzles me a bit:
"...expanded in terms of solute concentration $c$ (in gramms per unit volume)...
"...Thus, by use of the…
