摘要：
The present invention relates to provide crystalline copolymer of propylene and butene-1 with an essentially syndiotactic structure, which have crystalline structure even in the region where content of butene-1 is relatively high and which is excellent in stiffness.
A crystalline copolymer of propylene and butene-l with an essentially syndiotactic structure, the copolymer containing from 31 to 99 mole % of butene-l and having an intrinsic viscosity [η] of from 0.5 to 10 dl/g when measured in tetralin at 135°C and a crystalline structure.
