of the amino acid where X is a number from 20 to 80, uses as catalyst a composition comprising a polymer consisting of repeating monomer units of the laevorotatory form of the amino acid acid and a polymer consisting of repeating monomer units of the dextrorotatory form of the amino acid....
There may be 01-10% moles salt based on A. M may be Na, K, or Li. Also present may be an inert liquid diluent. A long list is given of aminoacids from which A may be derived. The reaction temperature may be from -20 C. up to the solvent b.p. 展开 ...

We delineated the MCAK-binding domains of NuSAP by performing further immunoprecipitation assays with a series of truncated mutants of NuSAP. Deletion of amino acids 433-441 from the C-terminal of NuSAP resulted in a marked abolishment of the interaction between NuSAP and MCAK, confirming that...
as its ability to form coordination bonds with metals to synthesise Cu and Ni nanoparticles [15]. The addition of d-block metal ions also has a significant effect on the polymer formation reaction itself. This is because transition metal ions such as Lewis acids are catalysts for the Michael ...
Poly( L -lactide)- block- poly( L -amino acids) block copolymers were prepared via polymerization of 伪-amino acid N -carboxyanhydrides with amino-terminated poly( L -lactide)s as macroinitiators. Two types of macroinitiators were used,... M Gotsche,H Keul,Hartwig Hoecker - 《Macromolecul...
Truly sustainable plastics require renewable feedstocks coupled with efficient production and end-of-life degradation/recycling processes. Some of the most useful degradable materials are aliphatic polyesters, polycarbonates and polyamides, which are oft
The preparation of N-carboxyanhydrides of α-amino acids using bis(trichloromethyl)carbonate A synthesis of the N-carboxyanhydrides (NCA's) of several 伪-amino acids using bis(trichloromethyl) carbonate, 1, is reported. The triphosgene is used to s... William,H.,Daly,... - 《Tetrahedron Le...
Types of RDRP There are in principle three ways to reversibly deactivate a reactive centre. By a reversible combination reaction, a reversible abstraction reaction, or a reversible addition reaction (Figure 2). The three most common forms of RDRP – Aminoxyl-Mediated Radical Polymerisation, Atom-Tr...
