APPENDIX
52. A propylene polymer having such properties that:
a melt flow rate (MFR) of said polymer at 230EC under a
load of 2.16 kg is in the range of 0.1 to 500 g/10 min,
a pentad isotacticity M obtained from the following
5
formula (1) using absorption intensity Pmmmm and Pw in a C-13
NMR spectrum of a boiled heptane-insoluble component contained
in said polymer is in the range of 0.970 to 0.995,
a pentad tacticity M obtained from the following formula
3
(2) using absorption intensity Pmmrm, Pmrmr, Pmrrr, Prmrr,
Prmmr, Prrrr and Pw in a C-NMR spectrum of a boiled heptane-13
insoluble component contained in said polymer is in the range
of 0.0020 to 0.0050, and
a crystallinity of a boiled heptane-insoluble component
contained in said polymer is 65% to about 79.3%;
M = Pmmmm
5
Pw (1)
wherein
Pmmmm is absorption intensity of methyl groups present in
the third unit among continuous five propylene units which are
bonded to each other with meso form, and
Pw is absorption intensity of all methyl groups in a
propylene unit;
M = Pmmrm + Pmrmr + Pmrrr + Prmrr + Prmmr + Prrrr
3
Pw (2)
wherein
Pmmrm is absorption intensity of methyl groups present in
the third unit among continuous five propylene units
represented by m m m k kin which m and k are each a propylene unit,
