Disclosed is a blood-compatible polymer represented by Formula 1. A polymer obtained by grafting a fluorinated methacrylate onto a polyvinylidene fluoride copolymer and provided in one aspect of the present invention is a polymer with blood compatibility, and may provide a blood-compatible material with hydrophobicity. In addition, it is possible to provide a material with controlled contact angle and surface energy properties by controlling the hydrogen fluoride length of the fluorinated methacrylate monomer for modification. Furthermore, it is possible to provide coating with controlled surface properties and blood compatibility through a simple process. Furthermore, it is possible to provide a freestanding polymer film with blood compatibility.

The present invention generally relates to vulcanization compositions used to vulcanize elastomeric articles, where the vulcanization compositions have reduced allergenic potential as compared to elastomeric articles formed using vulcanization compositions having non-fugitive accelerators. The present invention also relates to elastomeric articles formed using the vulcanization compositions. The invention further relates to methods for making a reduced-allergenicity vulcanization composition, and to methods for using the vulcanization compositions to vulcanize elastomeric articles.
