- A New Four-Arm Organosiloxane with Thermopolymerizable Trifluorovinyl ether Groups: Synthesis and Conversion to the Polymer with both Low Dielectric Constant and Low Water Uptake
Yumeng Xin, Jiajia Wang, Kaikai Jin, Yijie Luo, Junfeng Zhou, Yuanqiang Wang, Jing Sun, Shijun Zheng and Qiang Fang
Version of Record online: 26 APR 2017 | DOI: 10.1002/macp.201700010
A new fluoro-containing polysiloxane showing low dielectric constant, low water uptake, high transparency, and high thermostability is successfully synthesized by direct thermocrosslinking of a four-arm organosiloxane having thermopolymerizable trifluorovinyl ether groups.
- Structure Formation of Binary Blends of Amphiphilic Block Copolymers in Solution and in Bulk
Maryam Radjabian, Clarissa Abetz, Birgit Fischer, Andreas Meyer, Brigitte Lademann and Volker Abetz
Version of Record online: 25 APR 2017 | DOI: 10.1002/macp.201600587
Solutions of block copolymer blends show mixed microdomains above the critical micelle concentration and show a long period in the bulk, which depends on the number averaged molecular weight with a power law. This scaling behavior differs from the scaling behavior of the surface structure of integral asymmetric membranes made from similar blends.
- ABA and BAB Triblock Copolymers Based on 2-Methyl-2-oxazoline and 2-n-Propyl-2-oxazoline: Synthesis and Thermoresponsive Behavior in Water
Anna Zahoranová, Miroslav Mrlík, Katarína Tomanová, Juraj Kronek and Robert Luxenhofer
Version of Record online: 18 APR 2017 | DOI: 10.1002/macp.201700031
The preparation of triblock copolymers composed of hydrophilic 2-methyl-2-oxazoline and thermoresponsive 2-n-propyl-2-oxazoline is described. The copolymers exhibit temperature-driven micellization and aggregation, as well as temperature-induced increase in viscosity. The thermoresponsive behavior in water depends on composition, molar mass, concentration, and position of blocks.
- Coordinative Layer-by-Layer Assembly of Thin Films Based on Metal Ion Complexes of Ligand-Substituted Polystyrene Copolymers and Their Use as Separation Membranes
Gülara Krieger and Bernd Tieke
Version of Record online: 18 APR 2017 | DOI: 10.1002/macp.201700052
Polystyrene copolymers with terpyridine and bis(methylbenzimidazolyl)pyridine ligands in the side chain are studied on metal ion coordination in solution and coordinative sequential assembly of films and membranes. Permeation across the membranes and separation of ions and aromatic molecules are investigated.
- Branching Analysis of Comb-Shaped Polystyrene with Long Chain Branches
Sanghoon Lee and Taihyun Chang
Version of Record online: 18 APR 2017 | DOI: 10.1002/macp.201700087
Chain branching analyses are carried out with well-defined PS random combs with 1-4 long branches in a good and a theta solvent, respectively. The relationship of g′ = gε (g (Rg2)B/(Rg2)L, g′ [η]B/[η]L) works reasonably well with ε ~1 in tetrahydrofuran and ~0.66 in diethyl malonate while the theoretical grw does not agree well with gexp.
