2018-04-01

A series of 8‐(2,6‐dibenzhydryl‐4‐R‐phenylimino)‐5,6,7‐trihydroquinoline ligands have been prepared in which the nature of 4‐R substitutions vary from electron withdrawing to electron donating. The treatment with NiCl2.6H2O or (DME)NiBr2 afforded the correspo...

PET‐RAFT as a facile strategy for preparing functional lipid–polymer conjugates

10.1002/pola.29007

2018-04-01

From readily available starting materials, we report a facile synthesis of lipid–polymer conjugates (LPCs). Easy access to multigram quantities of a dialkyl lipid chain transfer agent allows a range of LPCs to be prepared bearing well‐defined hydrophilic poly...

Polyurethane elastomers based on amphiphilic poly(caprolactone)‐b‐poly(butadiene)‐b‐poly(caprolactone) triblockcopolyols
