(JACS)Rare Earth Metal-Mediated Group-Transfer Polymerization: From Defined Polymer Microstructures to High-Precision Nano-Scaled Objects
关键字：Rare Earth Metal, Group-Transfer Polymerization, 2-isopropenyl-2-oxazoline, 2-vinylpyridine
Poly(2-isopropenyl-2-oxazoline) (PIPOx) and poly(2-vinylpyridine) (P2VP) have been efficiently synthesized using bis(cyclopentadienyl)methylytterbium (Cp2YbMe) as catalyst. The polymerizations of 2-isopropenyl-2-oxazoline (IPOx) and 2-vinylpyridine (2VP) follow a living group-transfer polymerization (GTP) mechanism, allowing a precise molecular-weight control of both polymers with very narrow mole...

支化高分子溶液在剪切下的应力硬化
关键字：branch polymer, rheology, non-Gaussian stretching, strain hardening
We show for the first time that entangled polymeric liquids containing long-chain branching can exhibit strain hardening upon startup shear. As the significant long-chain branching impedes chain disentangle- ment, Gaussian coils between ent...
