Abstract
Polyurethanes (PU) are synthetic materials with large structural possibilities and mechanical adaptability that have promising perspectives in medical applications. This paper is focused on the hydrolytic stability and biocompatibility of poly(ester-urethane) and poly(ether-urethane) membranes blended with hydroxypropylcellulose (HPC). FTIR analysis and extended biocompatibility tests were performed. Based on our in vitro results this PU sample is expected to promote a better biological tolerance and lower pro-inflammatory reaction in vivo. Keywords: HPC-modified polyurethanes, hydrolytic stability, cytotoxicity, pro-inflammatory potential
