The amino end groups were introduced into the copolymer after the removal of the DTB end groups by reduction with NaBH4, followed by reaction of the resultant sulfanyl groups with AEMI-TFA and by addition of an amount of DIPEA equivalent to the amount of TFA in AEMI-TFA.
The low dispersity (1.1) and the functionality of the amino end groups (0.9) close to the unity predicted copolymer P3 to be effective and highly valuable in the synthesis of HMW star polymers.
Semitelechelic polymers containing amino end groups were used as polymer grafts attached via amide bonds to the bis-MPA dendrimer core to form star-like molecular structures with synthesis-controlled molecular weights.
In the melt blending process, PB-g-MAH reacts with PA66 through their maleic anhydride groups and the amino end groups, which is confirmed by FTIR and the melt How index.
Then during the melt blending process the MAH groups of PB-g-MAH can react with the amino end groups of PA66 and form a new graft polymer PB-g-PA66, as being proved by the FTIR and MFI analysis.
PB-g-MAH promotes the compatibility of PA66/ABS blend and enhances the interfacial adhesion greatly by the entanglement with PB chain in ABS and graft of PA66 through its amino end groups.
Alpha-helices are green cylinders; arrows point from the free amino end to the free carboxyl end.
Beta-pleated sheets (strands) are orange arrows pointing from the free amino end to the free carboxyl end.
In the sequence/alignment viewer, the free amino end is on the left and the free carboxyl end is on the right.
Highlight some amino acids at the free amino end of the protein.
