FIBER-REINFORCED PROPYLENE RESIN COMPOSITION

摘要

[OBJECT] The invention provides a fiber reinforced propylene resin composition having interfacial adhesion between a propylene resin and a reinforcing fiber and capable of preparing molded articles having high mechanical properties. [MEANS FOR ACHIEVING THE OBJECT] The fiber reinforced propylene resin composition comprises:
(A) 1 to 75 % by weight of a reinforcing fiber,
(B) 0.01 to 10 % by weight of a first propylene resin containing 50 to 99 % by mol of a constituting unit derived from propylene of an olefin component,
(C) 0.01 to 10 % by weight of a second propylene resin at least containing a carboxylic acid salt bonded to a polymer chain and
(D) 5 to 98.98 % by weight of a third propylene resin, wherein the order of the weight average molecular weights Mw of the components (B), (C) and (D) satisfy the following relation;
component (D) > component (B) > component (C).
