Title:
RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2002/032996
Kind Code:
A1
Abstract:
A resin composition comprising (1) 100 parts by weight of a propylene block copolymer which is composed of 1 to 70 wt% of a component eluted at 100 °C or above and 99 to 30 wt% of a component eluted at lower than 100 °C as determined by the temperature raising elution fractionation method with the higher -temperature eluted component being constituted of 100 to 90 mole % of propylene monomer units and 0 to 10 mole % of ethylene monomer units and the lower-temperature eluted component being constituted of 90 to 50 mole % of propylene monomer units and 10 to 50 mole % of ethylene monomer units, satisfies the relationship: log((Mw/Mn) x MFR?0.33¿)= 0.57 to 1.5 [wherein MFR is melt mass flow rate of the copolymer; and Mw and Mn are weight- and number-average molecular weights of the copolymer respectively as determined by gel permeation chromatography, and has a weight-average molecular weight (Mw) of 80,000 to 1,500,000, and (2) 1 to 100 parts by weight of a copolymer comprising 5 to 25 wt% of aromatic vinyl units and 95 to 75 wt% of conjugated diene units which are at least partially hydrogenated.
