    摘要: The present invention relates to a class of acid functionalized gradient block copolymers, processes for obtaining them and to their uses including but not limited to hair fixatives, toughening agents, and adhesives. Surprisingly, the applicants have discovered the aforementioned class of acid functionalized gradient block copolymers have advantageous properties and can find utility in a wide variety of application areas. These polymers are easily prepared by sequential monomer addition (i.e., “one-pot” synthesis) and the process does not require any post polymerization modification steps. The aforementioned polymers are derived from commonly utilized monomers. The use of common monomers provides both an economic advantage and an inherent safety advantage, e.g., the common monomers are considered biocompatible.

    摘要: The invention relates to an amphiphilic block copolymer having an increased speed of water adsorption. The non-water soluble copolymer, having a hydrophilic middle block and hydrophobic endblocks, has a high rate water transmission and/or permeation. The increase in rate is due to neutralization, or partial neutralization of the hydrophilic block of the copolymer. Furthermore, the absorption rate can be controlled by the extent of the neutralization. Another aspect of the invention is the use of co-monomers and/or additives to further increase or tailor the water absorption properties. The use of additives and comonomers is also shown to enhance the processability of the disclosed polymer composition.
