The invention provides for a process for the preparation of an advanced epoxy resin by reaction of a compound having on average more than one epoxy group per molecule and a compound having on average one or more hydroxyl group or carboxyl group per molecule in the presence of a catalyst at elevated temperature, the process comprising (1) mixing the epoxy compound, the hydroxyl compound or the carboxyl compound and the catalyst, and (2) transferring the mixture as a feedstream to a surface which is at least intermittently moving with respect to the feedstream. In a preferred embodiment an endless conveyer belt with additional heating means and optional cooling means are used.

Advanced epoxy resin from mixing polyepoxide and OH- or COOH-compound as feedstream

The invention provides for a process for the preparation of an advanced epoxy resin by reaction of a compound having on average more than one epoxy group per molecule and a compound having on average one or more hydroxyl group or carboxyl group per molecule in the presence of a catalyst at elevated temperature, the process comprising (1) mixing the epoxy compound, the hydroxyl compound or the carboxyl compound and the catalyst, and (2) transferring the mixture as a feedstream to a surface exposed to an elevated temperature sufficient to produce an advanced epoxy resin which is at least intermittently moving with respect to the feedstream. In a preferred embodiment an endless conveyer belt with additional heating means and optional cooling means are used.

Copolymerization of dicyclopentadiene with norbornene derivatives

An improved process for the anionic extruder polymerization of ethylenically unsaturated compounds in the presence of an organoalkali metal compound initiator employs relatively high reaction temperatures but relatively short residence times in the extruder.

Anionic extruder polymerization process

A process for preparing a blend of a norbornene polymer and a vinyl polymer, the process comprising (a) injecting into a mold a reaction mixture comprising from about 30 to about 70 weight percent, based on the total monomer weight, of at least one substituted or unsubstituted norbornene monomer, from about 70 to about 30 weight percent of at least one polymerizable monomer, a metathesis catalyst system comprising a transition metal catalyst and a cocatalyst, and a free radical initiator, and (b) subjecting the reaction mixture to temperature conditions to sequentially initiate polymerization of the norbornene monomer and the vinyl monomer.

Process for the preparation of polymer blends
