Study of blood compatible polymers. II. poly(N,N-disubstituted) acrylamides.
Poly(N,N-disubstituted) acrylamides with both hydrophilic and hydrophobic groups as substituents were synthesized. Different degrees of hydrophilicity were achieved by varying the bulk of the hydrophobic substituent. N-alkyl, N-(2-hydroxyethyl) acrylamides with alkyl substituents propyl (PROPAAm), octyl (OCTAAm) and benzyl (BENAAm) were synthesized. The swelling capacity of the polymers decreased with increase in bulk of the hydrophobic substituent. In vitro studies showed that the surfaces of these polymers did not induce platelet aggregation. Cell compatibility of these polymers was assessed by following the growth of human umbilical cord fibroblast cells. Pronounced cell growth and spreading was observed on the surfaces of polyOCTAAm and polyBENAAm. The relatively low cell growth on polyPROPAAm was ascribed to its high water content.
