摘要：

This report presented a new generation of UV-crosslinking solvent-bawd pressure-sensitive adhesive (PSA) based on photoinitiator-grafted polystyrene-block-polybutadieiie-block-polystyrene (SBS). The SBS, onto which the 4-maleimidobenzophenone (4-MBP) as photoinitiator was grafted, was used as the main component of a PSA. After the UV-crosslinking, a crosslinked structure was formed between polymer chains. FTIR showed that the photoinitiator monomer was successfully grafted onto the hydrophobic polymer. The grafting ratio could be facilely controlled by adjusting the feed amounts of the BPO initiators. The tests of adhesion properties indicated that the 1800 peel strength. shear persistent adhesivity and tack property were in the useful range for biomedical applications.
