Compositions for use in microelectronic applications:    R10, R11, R12, R13 are independently alkoxyl, hydroxyl, halide, OC(O)R, OC(O)OR, wherein R is alkyl or a substituted alkyl.

Compositions and antireflective coatings for photolithography

The invention provides compositions comprising at least one propylene-based polymer, at least one peroxide and at least one coagent. In a preferred example, a composition comprising at least one propylene-based polymer, at least one peroxide, at least one grafting agent, and at least one coagent, and wherein the at least one coagent has a substituted carbon-carbon double bond structure selected from the group consisting of structures (I), (II), (III), (IV) and (V) as follows, including cis and trans isomers wherein D1, D2, D3 and D4 are each, independently, one of the following: (a) a hydrocarbon substituent containing a heteroatom with a nonbonding pair of electrons, and where the heteroatom with the nonbonding pair is directly attached to the carbon-carbon double bond, or (b) a hydrocarbon substituent containing a carbon-carbon pi bonding pair, and where the first carbon of the carbon-carbon pi bonding pair is directly bonded to the carbon-carbon double bond; and wherein the R1, R2 and R3 are each, independently, H, a hydrocarbon substituent, or a substituted hydrocarbon substituent; and wherein R1, R2 and R3, each, independently, does not have the same chemical structure as D1, D2, D3 or D4; and wherein the molar ratio of the 'coagent(s)' to 'free radicals formed from the peroxide(s)' is from 0.5:1 to 5:1; and wherein the coagent selected from structures (I)-(V) does not contain only one phenyl group, or does not contain only one furyl group. 

Functionalized polymers, articles prepared therefrom, and methods for making the same

The invention relates to functionalized interpolymers derived from base olefin interpolymers, which are prepared by polymerizing one or more monomers or mixtures of monomers, such as ethylene and one or more comonomers, to form an interpolymer products having unique physical properties. The functionalized olefin interpolymers contain two or more differing regions or segments (blocks), resulting in unique processing and physical properties.

Novel organic ion-exchange polymers and membranes formed from these polymers provide improved performance in electrolytic cells. The membranes exhibit an expanded micro-structure as the result of the removal of organic groups previously reacted with the ion-exchange groups of the polymer. The polymers are also useful in finely divided form as catalysts or deposited on a catalyst support. When formed into sheets, the polymers are useful as membranes in the separation of miscible liquids and in the separation of gases.

Ion-exchange polymers having an expanded microstructure

This invention discloses improved heterogeneous acid catalysts and a method for preparing these catalysts. A heterogeneous acid catalyst has been prepared by coating a carrier with an aqueous emulsion containing a fluorocarbonsulfonic acid polymer in the sulfonyl fluoride form, removing the excess water, heating to a temperature above the softening point of the polymer for a time, and then converting the polymer to the active sulfonic acid form. The substrate has pores of about 0.1 micrometers or greater and a surface area of about 20 m.sup.2 /g or less.

Supported fluorocarbonsulfonic acid polymers and an improved method for

This invention discloses improved heterogeneous acid catalysts and a method for preparing these catalysts. A heterogeneous acid catalyst has been prepared by treating a carrier material with a solution containing a fluorocarbonsulfonic acid polymer dissolved in a suitable solvent, removing the solvent, and heat treating the coated carrier in such a way so as to prevent the polymer from being leached off the carrier. The final heat treatment of the composition to prevent the polymer from redissolving comprises an improvement in the preparation of a heterogeneous catalyst.
