Random hydrophilic-hydrophobic copolymers
We study a single statistical amphiphilic copolymer chain AB in a selective solvent (e.g. water). Two situations are considered. In the annealed case, hydrophilic (A) and hydrophobic (B) monomers are at local chemical equilibrium and both the fraction of A monomers and their location along the chain can vary, whereas in the quenched case (which is relevant to proteins), the chemical sequence al...
متن کاملDNA multiblock copolymers.
Single stranded (ss) DNA block copolymers were applied to synthesize DNA multiblock architectures by hybridization; these polymeric bioorganic hybrids were characterized by gel electrophoresis and MALDI-TOF mass spectrometry.
متن کاملPolystyrene/wood composites and hydrophobic wood coatings from water-based hydrophilic-hydrophobic block copolymers
D. J. Gardner Department of Forest Management and Advanced Engineered Wood Composites Center, University of Maine, Orono, ME 04469, USA Abstract The combination of synthetic thermoplastic polymers and wood is normally problematic because wood surfaces are hydrophilic while typical thermoplastic polymers are hydrophobic. A possible solution is to use block copolymer coupling agents. In this work...
متن کاملPhase behavior of symmetric linear multiblock copolymers
Molecular-dynamics simulations are used to study the phase behavior of a single linear multiblock copolymer with blocks of Aand B-type monomers under poor solvent conditions, varying the block length N , number of blocks n, and the solvent quality (by variation of the temperature T ). The fraction f of A-type monomers is kept constant and equal to 0.5, and always the lengths of A and B blocks a...
متن کاملThermogelling of double hydrophilic multiblock and triblock copolymers of N,N-dimethylacrylamide and N-isopropylacrylamide: chain architectural and Hofmeister effects.
A series of thermoresponsive double hydrophilic (AB)(n) multiblock and ABA triblock copolymers of N,N-dimethylacrylamide (DMA) and N-isopropylacrylamide (NIPAM) with varying sequence lengths were synthesized via successive reversible addition-fragmentation chain transfer (RAFT) polymerizations by employing polytrithiocarbonate as the chain transfer agent. Previously, we reported that multiblock...
