Development of Blood Compatible Composite Using MPC Copolymer and Polyolefin for Non-PVC Blood Bag Application
E-mail:
Polyolefin is a good candidate for a blood bag material alternative to the poly (vinyl chloride) (PVC) blood bag that contains di-2-ethylhexyl phthalate (DEHP). However, polyolefin readily adsorbs some plasma proteins and platelets. To prevent these undesired adsorption, 2-methacryloyloxyethyl phosphorylcholine (MPC) ? hydroxyethyl methacrylate (HEMA) ? lauryl methacrylate (LMA) copolymers with varying monomer ratios were synthesized and used as blended material for additives to reduce platelet adsorption. Platelet adsorptive properties were reduced by blending MPC copolymers with polyolefin and confirmed by the platelet adhesion test and the activated partial thromboplastin time (APTT) test.
