Appeal No. 1997-3497 Page 3
Application No. 08/312,295
proplylene polymer of said propylene polymer
ply having:
an n-heptane-insoluble fraction which
has a triad-related chain isotaxy index,
measured by means of 13C-NMR spectrosopy, of
about 95 to about 96%,
a modulus of elasticity of the film
structure in the longitudinal direction which
is greater than 2,500 N/mm2 and a modulus of
elasticity of the film structure in the
transverse direction which is greater than
4,000 N/mm2, said moduli of elasticity having
been determined in accordance with German
Engineering Standard DIN 53 457;
said propylene polymer-containing ply
containing less than 1% by weight, based on
the total weight of the film structure, of
hydrocarbon resin having a molecular weight
less than 5,000.
