precision-branched polyethylene structures, the branch being placed on each 21st carbon and ranging in size from a methylgroup to an adamantyl group. The crystalline unit cell is shifted from orthorhombic to triclinic, depending upon the nature of the precision branch. Further, the branch can be positioned either in the crystalline phase or in the amorphous phase of polyethylene, a morphology change
