摘要:
The present invention relates to a process for the preparation of a graft copolymer comprising a polyolefin main chain and one or multiple polymer side chains, the process comprising the steps of: copolymerizing at least one first type of olefin monomer and at least one second type of metal-pacified functionalized olefin monomer to obtain a polyolefin main chain having one or multiple metal-pacified functionalized short chain branches, and reacting the polyolefin main chain having one or multiple metal-pacified functionalized short chain branches with at least one metal substituting agent to obtain a polyolefin main chain having one or multiple functionalized short chain branches; and forming one or multiple polymer side chains on the polyolefin main chain, wherein as initiators the functionalized short chain branches on the polyolefin main chain are used to obtain the graft copolymer. The invention also relates to the products obtained therefrom.

摘要:
An immersion upper layer film composition is provided which exhibits sufficient transparency for the exposure wavelength 248 nm(KrF) and 193 nm(ArF), can form a protective film on the photoresist film without being intermixed with the photoresist film, is not eluted into water used during immersion exposure to maintain a stable film, and can be easily dissolved in an alkaline developer. The composition applied to coat on the photoresist film when using an immersion exposure device which is irradiated through water provided between a lens and the photoresist film, the composition comprises a resin forming a water-stable film during irradiation and being dissolved in a subsequent developer, and a solvent containing a monovalent alcohol having 6 or less carbon atoms, and the resin contains a resin component having an alcoholic hydroxyl group on the side chain containing a fluoroalkyl group on at least the carbon atom of ±-position.
摘要:
Un monomère présentant une fonctionnalité polaire par exemple à travers un groupe hydroxyle ou autre groupe fonctionnel est protégé durant la polymérisation en présence de catalyseurs hautement actifs grâce à l'utilisation d'un groupe de silane alkyle protecteur, lequel est retiré après la polymérisation de façon à rétablir la fonctionnalité du groupe. Le polymère ainsi obtenu comprendra des groupes fonctionnels sur sa structure centrale. Les groupes fonctionnels peuvent réagir avec des colorants traditionnels et/ou exercer d'autres fonctions et entrer en réaction avec d'autres composés réactifs. De nouveaux polymères sont produits pour être utilisés dans des systèmes du type Ziegler-Natta.
