This report describes the aqueous solution self-assembly of a series of polystyrenem-b-poly(L-lysine)n block copolymers (m = 8-10; n = 10-70). The polymers are prepared by ring-opening polymerization of e-benzyloxycarbonyl-L-lysine AT-carboxyanhydride usin ...
Inline conversion measurements in chem. reactions are in general and esp. in polymn. reactions necessary for process monitoring and control. For polymn. monitoring, the sound propagation (UPV) can be related to the texture of the bulk with a high accuracy. ...
A new synthetic strategy for the preparation of highly branched, or dendritic-graft, polypeptides is presented. The synthetic strategy is based on a repetitive sequence of ring-opening copolymerization and deprotection steps. Comonomers for the ring-openin ...
In this contribution, the synthesis of two novel amino-functionalized terrylene and quaterrylene diimide derivatives is described. These chromophores have been used as initiators for the ring-opening polymerization of N€-benzyloxycarbonyl-L-lysine N-carbox ...

The reinforcement potential of pulp fibres is presently not fully explored in thermoplastic composites. One of the reasons is that currently used processing methods comprise several severe thermomechanical steps inducing premature degradation of the fibres ...
This paper describes the synthesis of several novel water-soluble highly branched polypeptides. The synthesis starts with the ring-opening polymerization of ε-benzyloxycarbonyl-L-lysine N-carboxyanhydride (Z-Lys NCA) or ε-trifluoroacetyl-L-lysine N-carboxy ...
A high mol. wt. water sol. acrylamide based polymer having improved flocculating and dewatering properties is provided. The polymer is prepd. by a process in which a small quantity of a chain branching agent is added to the polymn. reaction mixt. continuou ...

The synthesis and supramolecular organization of a novel class of rod-coil type diblock oligomers will be discussed. The diblock oligomers consist of a rodlike α-helical oligopeptide segment that is conjugated to an oligo(styrene) coil. In comparison with ...
Two series of novel, four-arm, star-shaped polypeptides were prepared via the ring-opening polymerization of γ-benzyl-L-glutamate N-carboxyanhydride and ε-benzyloxycarbonyl-L-lysine N-carboxyanhydride with a tetra-amino-substituted perylene fluorophore as ...
