Abstract
Terpolymers composed of ethyl acrylate (EA), methoxypolyethyleneglycol methacrylate (MPEGMA) and polydimethylsiloxane methacrylate (PDMSMA) were synthesized by the radical polymerization technique. The high molecular mobilities for these terpolymers were shown by dynamic contact angle and adhesion tension measurement. Three properties of pressure sensitive adhesive, including 180-degree peel strength, probe tack and holding power, for these terpolymers were good. The blood compatibility of these terpolymers was also investigated. The thrombi were not observed on the terpolymer surface after immersion in blood, while many blood clusters were observed on a polystyrene (PSt) surface. After immersion in platelet-rich plasma (PRP), a few adhered platelets were observed on terpolymer surface but they did not deform and maintained their spherical form, while many platelets were observed on polystyrene. It was found that they had a significant blood compatibility.
