COMPOSITION CONTAINING NETWORK STRUCTURE BASED ON DENDRIMER CONTAINING HYDROPHILIC AND HYDROPHOBIC NANOSCOPIC DOMAINS

摘要

PROBLEM TO BE SOLVED: To obtain the subject composition capable of forming an elastomer film having excellent transparency and thermal and mechanical stability and exhibiting unique separation and swelling characteristics by including a network structure based on a copolydendrimer having a hydrophilic inner part and a hydrophobic organic silicon outer layer. ;SOLUTION: This composition contains a crosslinked product of a copolydendrimer (Z) laminated in radial direction and containing a hydrophilic inner part (e.g. polyamide amine and polypropylene imine) and a hydrophobic organic silicon outer layer having a reactive terminal group [e.g. NH₂, a group of the formula NR₂ (R is a 1-6C alkyl, etc.), a group of the formula R'SH (R' is a 1-6C alkylene, etc.), etc.]. The component Z is produced by reacting a hydrophilic dendrimer having NH₂ surface group with an organic silicon compound.;COPYRIGHT: (C)1999,JPO
