✦ Synopsis

This paper describes our recent developments of block and graft copolymers prepared by the cationic ringopening polymerization of 2-oxazolines. First, the mechanistic aspects of polymerization are mentioned, in which terms of "electrophilic and nucleophilic polymerizations" are proposed. Then, preparations and properties of poly(z-acy1ethylenimine) chains from 2-oxazoline monomers are described.

They are (i) AB and BAB type block copolymers of 2-oxazolines for nonionic polymer surfactants, (ii) poly[(E-acetylethylenimine)-b-(oxyethylene)] for anti-electrostatic agents, (iii) cellulose diacetate having poly(z-acylethylenimine) graft chain for "compatibilizer" with commodity polymers, and (iv) polyethylenelvinyl acetate copolymer having poly(N-acy1ethylenimina) graft chain for blood-compatible polymeric materials.

## Abstract **Summary:** Commercial poly(styrene‐__co__‐acrylonitrile) (SAN) and poly(butadiene‐__co__‐acrylonitrile) (NBR) were functionalized with oxazoline groups through a reaction with 1,3‐aminoethylpropanediol (AEPD). Each of the two products, along with a third commercial poly(styrene‐__co__

## Abstract The surface compositions of a series of polystyrene‐__b__‐polydimethylsiloxane (PS‐__b__‐PDMS) and polystyrene‐__g__‐polydimethylsiloxane (PS‐__g__‐PDMS) copolymers were investigated using ATR‐FTIR and XPS technique. The results showed that enrichment of PDMS soft segments occurred on t
