Notes:
The concept of the breaking strength of a polymer chain is analyzed by means of a study of the dynamics of a rectilinear chain of monomers connected by Hookian bonds. A formalism is then developed whereby the average time to breaking of the chain can be calculated as a function of temperature and strain. An approximation to the exact solution of the resulting equations is discussed. It is concluded that correlations in space and time in the motion of the chain lead to breaking times that are not simple functions of the chain length. The predicted breaking times are appreciably smaller than those that would be found in a chain in which the thermal motions of the monomers were uncorrelated. © 1994 American Institute of Physics.
