The present invention relates to a polymer having a first monomer selected from the group consisting of: styrene, MMA, HEMA or MEMA and a second monomer selected from the group consisting of: GMA, DEAEA, DEAEMA, DMAA, BAEMA, 4-vinylpyridine, DMVBA, 1-vinylimidazole, DMAEA or a combination thereof as coating agent for a scaffold or a medical device, to promote cellular adhesion and/or cell growth or for the manufacture of yarns or threads. The polymer may further contain a third monomer selected from the group consisting of: BMA, DEGMEMA, DAAA and MMA. The invention also relates to a scaffold, a medical device, a yarn, a thread or a textile coated or manufactured with the polymers of the invention and relative methods.
