Abstract:
The present invention provides a method for preparing an olefin polymer which can exhibit excellent isotacticity in a high yield and thus is suitable for use in reinforcing a long fiber, and a long fiber comprising an olefin polymer produced according to the above preparation method.

Claim (Index 1):
