Synthesis and characterization of twin-tailed hydrophobic monomer N,N-di-n-dodecylacylamide;

5,AME-5 and AME- 10 were synthesized from AE and acrylamide(AM)in aqueous solution,based on different weight per- centage of the hydrophobic monomer.

The experiment shows that the high content of hydrophobic monomer makesthe inherent viscosity of the polymer decreases, that is, hydrodynamic volume of macromolecular chain group in the solution decreases and the hydrophobic association strengthened.

As a hydrophilic monomer in WPU synthesis,further study on the oligomers of polyether and polyester with sulphonate group was worthy.

Cross-linked Copolymer gels were successfully prepared by copolymerization of long alkyl chain acrylic ester (hexadecyl acrylate(HA), octadecyl acrylate(ODA),) and hydrophilic monomer (acrylic acid(AA), methacrylic acid(MAA), 2-hydroxy-ethyl ester(HEA)) , using absolute ethanol as a solvent, N,N' -methylene-bis-acrylamide (MBAA) as a cross-linking agent at 50@.

The water-borne technology for polyester is reviewed with using different hydrophilic monomers, including trimellitic anhydride, dimethylmalonic acid, UV curable hyperbranched waterborne polyester, as well as sulphonate monomer.

Hydrophobic-hydrophilic macroporous polydivinylbenzene/polyacrylethylenediamine interpenetrating polymer networks (PDVB/PAEM IPN) were prepared by the sequential suspension polymerization method.
