摘要： The present invention relates to cyclic polymers and their use in photolithographic applications. The cyclic polymers contain a pendant acid labile functional group and a functional group containing a protected hydroxyl moiety. The polymers are post modified by deprotecting the pendant hydroxyl moiety and reacting the deprotected hydroxyl containing moiety with a coreactant. The post-functionalized polymers find application in chemically amplified photoresist compositions.

摘要： The present invention concerns a process for producing a propylene polymer nucleated with a polymeric nucleating agent containing vinyl compound units. The method comprises modifying a catalyst by polymerizing a vinyl compound in the presence of said catalyst in a medium, which does not essentially dissolve the polymerized vinyl compound, and by continuing the polymerization of the vinyl compound until the concentration of unreacted vinyl compounds is less than about 0.5 wt-%. The thus obtained modified catalyst composition is used for polymerizing propylene optionally together with comonomers to produce in the presence of said modified catalyst composition. Modification of the catalyst according to the present invention will reduce production costs and provide highly reliable catalyst activity.

摘要： The invention pertains to benzocyclobutene resins having flame retardant properties. Such resins have a high glass transition temperature (Tg>250° C.), low moisture absorption, low dielectric constant, good mechanical properties, flame retardancy (meets or exceeds UL94 V-O and/or VTM-O requirements), and can be cast onto a reinforcement to prepare a laminate for use as a substrate for electronic circuitry. The flame resistant compound is reaction product of a halogen containing compound of the formulae R&Parenopenst; DA)n or R&Parenopenst; DA&Parenclosest;n R2 wherein R is a halogen containing aromatic group, a halogen containing aliphatic group or a combination thereof; R2 is hydrogen, an aromatic group, an aliphatic group or an combination of an aromatic group and an aliphatic group which may contain halogen atoms; DA is a Diels-Alder reactive diene or a group that can act as a dienophile in a Diels-Alder reaction; and n is greater than or equal to 1; with a benzocyclobutene compound.
