## Abstract Polyurethanes containing __z__βlysine segments in the main chain (PULL) were synthesized from 4,4β²βdiphenylmethyl diisocyanate, poly(tetramethylene glycol), and __z__βlysine oligomer as a chain extender. PULL film was treated with a 10% HBrβacetic acid solution and subsequently with a s

## Abstract Three new amphiphilic phospholipid diols containing hydrophilic phosphatidylcholine analogues in the main chains and hydrophobic octadecyl, hexadecyl or dodecyl alkyl groups in the side chains were synthesized. The typical phospholipid diol based on an octadecyl group was further reacte
Novel polyetherurethaneureas containing tertiary amino groups in the side chains (PAEUU) were synthesized, quaternized with different alkyl halides (Q-PAEUU), and heparinized (H-PAEUU). The antithrombogenicity of PAEUU in uitro was improved by quaternization, and further by heparinization. The excel
