Abstract: A photosenstive resin composition is prepared by dispersing at least one of a hydrophobic polymer and a mixture of an oil-soluble photopolymerization initiator and a water-insoluble or sparingly water-soluble compound having at least one photoactive, ethylenically unsaturated group in an aqueous solution that contains both a water-soluble polymer and a diazo resin is obtained by condensing a water-soluble salt of an optionally substituted 4-diazodiphenylamine with formaldehyde in the presence of sulfuric acid and phosphoric acid. This photosensitive resin composition gives a photosensitive film having excellent stability over time and a wide exposure latitude. By adding a specific fluorine compound to the photosensitive resin composition, a screen plate has an excellent discharge performance.

Abstract: The present invention is directed to a coated biomedical device said micelle having a hydrophilic outer shell and a hydrophobic inner core, or a hydrophobic outer shell and a hydrophilic inner core said micelle comprised of a block copolymer having a HLB value ranging from about 1 to about 40. The medical device may have one coating thereon or multiple coatings. The present invention is also directed to the use of the micelle as a drug carrier.

Abstract: The invention provides a molded laminate with excellent adhesive strength which comprises an adhesive polymer composition layer and a gas-barrier resin layer comprising a polyamide resin or an ethylene-vinyl alcohol copolymer, the adhesive polymer composition layer comprising a modified polyester type elastomer obtained by modifying a saturated polyester type thermoplastic elastomer having a polyalkylene ether glycol segment content of 58 to 73% by weight with an unsaturated carboxylic acid or a derivative thereof in the presence of a radical generator.

Abstract: An object of the invention is to provide a molded laminate by using a thermoplastic polymer composition exhibiting excellent heat fusion-bond properties, particularly excellent heat fusion-bond properties in a high-temperature atmosphere, to a thermoplastic resin, particularly a polyamide resin or an ethylene-vinyl alcohol copolymer.

Abstract: Disclosed are polyoxyethylene derivatives having different functional groups at both ends of the molecule represented by the following formula (I) and a process for producing the derivatives by anionic living polymerization. The present invention provides polymers which are especially suitable for use as medical materials. wherein A′ and B′ are organosilyl type amino-protecting groups, R is a hydrogen atom or a C1-6 alkyl group, and Y is a hydrogen atom, an alkali metal or a certain functional group.

Abstract: This invention provides a heterotelechelic oligomer or polymer which is represented by formula below: ##STR1## wherein R.sup.1 and R.sup.2 form an acetal, or, combined with each other, denote oxy (.dbd.O),p, m, n and q each denote a certain integer,L is a group which forms an ester, andZ denotes a certain functional group.This invention a so provides a process to produce the above oligomer or polymer by means of living polymeri-zation. Since this oligomer or polymer forms a high- molecular micelle which is stable in an aqueous solvent, said oligomer or polymer will be useful as a carrier for drug delivery.
