Abstract
A polypropylene resin composition containing (A) a polypropylene resin treatment product obtained by adding from (0.05) to (5) weight parts of an organic peroxide to (100) weight parts of a polypropylene resin with a melt flow rate of from (0.1) to (50) g/10 min and carrying out a melt treatment and (B) from (0.01) to (2) weight parts of an oxide of the group (2) or (12) metal of the periodic table or a metal alkoxide of defined formula to (100) weight parts of a resin content of the above polypropylene resin treatment product.
Claims3
A polypropylene resin composition containing (A) a polypropylene resin treatment product obtained by adding from 0.05 to 5 weight parts of an organic peroxide to 100 weight parts of a polypropylene resin with a melt flow rate of from 0.1 to 50 g/10 min and carrying out a melt treatment and (B) from 0.01 to 2 weight parts of an oxide of the group 2 or 12 metal of the periodic table or a metal alkoxide represented by the following general formula (I) to 100 weight parts of a resin content of the above polypropylene resin treatment product:
- M(R)m-n(OR′)n (I)
- wherein R and R′ each represent an alkyl group with from 1 to 20 carbon atoms, m is 3 or 4, n is an integer satisfying m≧n≧2, and M represents boron (B), aluminum (Al), silicon (Si), or a metal atom of the group 4 or 5 of the periodic table.
