• Note (General): Anionic living polymerization of four new monomers that serve as intermolecular chemical links between polymer chains are described, along with the wide applications of the resultant polymer alloys. Examples of the first monomer include three tertiary aminostyrenes. The corresponding poly(tertiary aminostyrene)s (PtAS) having a desired molecular weight and narrow molecular weight distribution were prepared. Crosslinked films of PtAS with p, p'-bis(chloromethyl)azobenzene (CAB) were prepared by quaternization. Photochemical isomerization of CAB incorporated in PtAS was investigated. The second monomer discussed is N-isopropyl-N-trimethylsilyl-4-vinylbenzylamine (ISBA). ISBA was anionically polymerized and subsequent deprotection of the trimethylsilyl protecting group produced poly (N-isopropyl-4-vinylbenzylamine) (PIBA) with a secondary amino group. The non-thrombogenic behavior of the corresponding poly (aminostyrene)-graft-oligopeptide graft copolymers was evaluated. The third monomer, (4-vinylphenyl)dimethylvinylsilane (VS), contains a silylvinyl group. To carry out a chemoselective polymerization of the styryl group of VS, a systematic study on anionic polymerization was carried out. Lithographic characterization shows the resultant polymer (PVS) acting as a negative working resist. Three (PVS-graft-polyisoprene)-block-polystyrene block-graft copolymers were prepared by a “grafting onto" process. The fourth monomer discussed is p-butoxystyrene. The deprotection of the tert-butyl protecting group from the corresponding polymer produces poly (p-hydroxystyrene) (PHSt). Two polystyrene-block-[PHSt-graft-poly (ethylene oxide)]-block-polystyrene block-graft copolymers were prepared by a “grafting from" process. Benzene-cast films formed clear and specific lamellar structures in which poly (ethylene oxide) is not crystallized.
