We have prepared an amphiphilic oxazoline block copolymer of hydrophilic poly(2-methyl-2-oxazoline) and hydrophobic poly[2-(2-perfluorooctyl)ethyl-2-oxazoline] chains. By controlling the length and composition of polymer chains, we found that this fl

A series of poly(N-acylethylenimines) with hydrocarbon and fluorocarbon side chains varying in length from 6 to 17 carbon atoms were prepared by cationic ring-opening polymerization of 2-oxazolines. The behavior of monolayers of these materials at th

Polymers derived from 2-[2-(perfluoroalkyl)ethyl]-2-oxazolines have been prepared in very good yields with molecular weights up to 50000. The polymers are crystalline with melting temperatures (Tm's) varying from 180 to 232°C depending on the length

A variety of acrylic and methacrylic acetal esters were synthesized by reaction of unsaturated carboxylic acids with vinyl ethers. The acetal esters were converted by radical polymerization and GTP to acid-labile homo- and copolymers. Coatings of the

Two synthetic routes were used for the preparation of aromatic poly(ether ketones): Friedel-Crafts acylation and aromatic nucleophilic substitution. The first route involved the reaction of diphenyl ether and terephthalic acid dichloride in trifluoro

Group transfer polymerization (GTP) and the related Aldol-GTP are new types of living polymerization mediated by silicon for precise control of polymer structure. The two processes are regenerative in that the reactions are accompanied by transfer of
