Graft copolymers with acid-sensitive

Polystyrene-PDMS block copolymers4l2), and poly(n-butyl methacrylate-acrylic acid)-PDMS graft copolymers 308) have been used as pressure sensitive adhesives. Hot melt adhesives based on polycarbonate-PDMS segmented copolymers 413) showed very good adhesion to substrates with low surface energies without the need for surface preparation, such as etching. 

Recently, different authors proposed the blend of soy protein with environmentally sensitive polymers to synthesize composite materials with intelligent features, which may result in new potential applications in the biomedical and pharmaceutical fields. Li et al. report the synthesis and self-assembly behavior in aqueous solution of thermally responsive graft copolymer (SPl-g-p(iV-isopropylacrylamide]] of soy protein isolate and N-isopropylacrylamide in aqueous solution by using ammonium persulfate as the initiator and mercaptoacetic acid as the protein unfolding agent (Li et al., 2010]. Alternatively, temperature-sensitive interpenetrating polymer network hydrogels based on... 

A recent trend is to design polymers with multiple functions including cationic units to bind nucleic acids as well as pH-sensitive carboxylic acids for endosomal dismption. Using a block copolymer architecture, comb-like polymers with cationic grafts were extended from aspartic acid units via a hydrazone linkers.The second block was composed of...
