The dynamic properties of viscoelastic materials during anharmonic loading

Abstract

and the curves of the second t ype are characterist ic of copolymers having a graft , l inear s t ructure , i.e. having a large propor t ion of M~--M2--M 2 bonds. (4) F rom the example of the systems po lyd ie thy leneg lyco l fumara te -v iny l acetate , and po ly l , 3 -bu ty l eneg lyco l fumara t e -v iny l ace ta te and s tyrene, it is shown tha t the me thod used for the de te rmina t ion of the copolymerizat ion constants of the po lyes t e r -v iuy l monomer systems gives sa t isfactory results.
