•changes in its mechanical properties with a decrease or an increase in molecular weight as a result of chain- scission or cross-linking of the polymer molecules.
The molecular weight and molecular weight distribution of a polymer can markedly affect its mechanical properties. While this has been recognized for a long time, quantitative studies have been relatively difficult to perform for a number of reasons. A major problem has been the characterization of

Mechanical Properties of Polymers . Strength. First, there is more than one kind of strength. A polymer sample has tensile strength if it is strong when one pulls on it. Tensile strength is important for a material that is going to be stretched or under tension. Fibers need good tensile strength. A polymer sample has compressional strength if it is strong when one tries to compress it

A physicist talking on mechanical properties of materials will obviously start from the properties which are simplest from the point of view of a mathematical physical description. These are the properties exhibited by the material at small deformations, so small that linear relations exist between
The mechanical properties of polymers are of interest in all applications where polymers are used as structural materials. Mechanical behavior involves the deformation of a material under the influence of applied forces. The simplest mechanical properties are those of homogeneous isotropic and purely elastic materials; their mechanical response can be defined by only two constants. For
