Title:
PROPYLENE RANDOM BLOCK COPOLYMER, RESIN COMPOSITIONS CONTAINING THE COPOLYMER, AND MOLDINGS OF BOTH
Document Type and Number:
WIPO Patent Application WO/2007/116709
Kind Code:
A1
Abstract:
A propylene random block copolymer (A) which has a melt flow rate of 0.1 to 100g/10min
and a melting point of 100 to 155°C, characterized by being composed of 90
to 60wt% of a segment (Dinsol) insoluble in n-decane at room temperature
and 10 to 40wt% of a segment (Dsol) soluble in n-decane at room temperature,
with Dinsol satisfying the following requirements (1) to (3) and Dsol
satisfying the following requirement (4) to (6); and moldings such as sheet,
film, injection moldings, hollow moldings, injection blow moldings, and fibers,
which are made by using the copolymer (A) or propylene resin compositions containing
the copolymer (A): (1) Dinsol has a molecular weight distribution
(Mw/Mn) of 1.0 to 3.5 as determined by GPC, (2) the content of skeletons resulting
from ethylene in Dinsol is 0.5 to 13% by mole, (3) the total content of
2,1- and 1,3-propylene units in Dinsol is 0.2% by mole or below, (4)
Dsol has a molecular weight distribution (Mw/Mn) of 1.0 to 3.5 as determined
by GPC, (5) Dsol has a limiting viscosity [η] of 1.5 to 4dl/g as
determined in decalin at 135°C, and (6) the content of skeletons resulting
from ethylene in Dsol is 15 to 35% by mole.
