Abstract

Abstract A crosslinked resin composition obtained by crosslinking a composition comprising (A) 95-10 wt.% of a propylene polymer and (B) 5-90 wt.% of an ethylene/α- olefin copolymer having the following properties (i) to (iv) and prepared by copolymerizing ethylene with an α-olefin having 3 to 12 carbon atoms in the presence of a catalyst, said catalyst comprising a solid component and an organoaluminum compound, said solid component containing at least magnesium and titanium: (i) Melt index 0.01 - 100 g/10 min (ii) Density 0.860 - 0.910 g/cm 3 (iii) Maximum peak temperature not lower than 100°C measured according to a differential scanning calorimetry (DSC) (iv) Insolubles in boiling not less than 10 wt.% n-hexane

Claim 2
Dependent Claim 112 words
A crosslinked resin composition obtained by crosslinking a composition comprising (A) 95-10 wt.% of a propylene polymer and (B) 5-90 wt.% of an ethylene/a-olefin copolymer having the following properties (i) to (iv) and prepared by copolymerizing ethylene with an α-olefin having 3 to 12 carbon atoms in the presence of a catalyst, said catalyst comprising a solid component and an organoaluminum compound, said solid component containing at least magnesium and titanium: (i) Melt index 0.01 - 100 g/10 min (ii) Density 0.860 - 0.910 g/cm 3 (iii) Maximum peak temperature not lower than 100°C measured according to a differential scanning calorimetry (DSC) (iv) Insolubles in boiling not less than 10 wt.% n-hexane
Claim 3
Dependent Claim 26 words
A crosslinked resin composition as set forth in claim 1, wherein the Q-olefin in the ethylene/α-olefin copolymer is an α-olefin having 3 to 6 carbon atoms.
Claim 4
Dependent Claim 30 words
A crosslinked resin composition as set forth in claim 1 or claim 2, wherein the weight ratio [(A)/(B)] of the propylene polymer (A) to the ethylene/α-olefin copolymer (B) is 80-10/20-90.
Claim 5
Dependent Claim 47 words
A resin composition obtained by adding a propylene polymer to a crosslinked resin composition as claimed in any one of claims 1 to 3 in such a range of an amount as satisfies the content of the ethylene/α-olefin copolymer (B) of. 5-90 wt.% in the resulting composition.
