Patent number: 6576684Abstract: Disclosed are compositions from which radically initiated oligomers/polymers having a controlled molecular weight, low polydispersity and a vinyl or dienyl end group are prepared. Further subjects of the invention are a process for controlled radical polymerization, oligomers/polymers obtainable by said process and the use of specific addition fragmentation agents for the polymerization process. The addition fragmentation agents are new in part and these are also subject of the present invention. The addition fragmentation agents are of the formula (Ia), (Ib) or (Ic) where Y is a group which activates the double bond towards Michael addition.Type: GrantFiled: February 15, 2001Date of Patent: June 10, 2003Assignee: Ciba Specialty Chemicals CorporationInventors: Vincent Desobry, Peter Murer, Anne Schuwey

Publication number: 20030099841Abstract: The present invention relates to a photocurable resin composition which contains a photocurable component and forms on a substrate a photocurable resin layer having a viscosity of 1000-500,000 Pa·s at 23° C. and 65% RH. This resin composition is formed into a photocurable resin layer, which is laminated onto a metal sheet to give a metal sheet with a photocurable resin layer laminated thereon. This metal sheet can be worked and converted into a metal part with a high-hardness protective coating laminated thereon upon irradiation with light or electron beams after working.Type: ApplicationFiled: September 16, 2002Publication date: May 29, 2003Inventors: Takeshi Watase, Yasuo Hirano, Kazuo Okumura, Atsushi Kihara, Yukihisa Komiya, Tadashige Nakamoto, Takahiro Kobayashi, Takeshi Ohwaki, Mika Nishida, Etsuji Ueno
