A method for preparing an article includes at least a first component of a polyolefin in conjunction with a second component of a polymer made by ring-opening metathesis polymerisation of norbornene type monomers. The method includes pre-treating a surface of the first component, applying a ring-opening metathesis polymerisable mixture of norbornene type monomers and a catalyst to the surface, and curing the ring-opening metathesis polymerisable mixture in contact with the surface, wherein the ring-opening metathesis polymerisable mixture has a &#x3b7;at 30&#xb0; C. of more than 9 sec. Articles such as a pipe line field joint or a protective element for a concrete tunnel lining element can be made using the method.

Methods for fabricating three-dimensional objects by 3D-inkjet printing technology are provided. The methods utilize curable materials that polymerize via ring-opening metathesis polymerization (ROMP) for fabricating the object, in combination with acid-activatable pre-catalyst and an acid generator activator. Kits containing modeling material formulations usable in the methods are also provided.

The present invention relates to sizing compositions, to glass fibers at least partially coated with such sizing compositions, to a variety of fiber glass products at least partially coated with such sizing compositions, and to composites formed from cycloolefins and reinforced with glass fibers at least partially coated with sizing compositions of the present invention. In one non-limiting embodiment, a sizing composition for glass fibers comprises a film-former comprising a polymer, wherein the repeating unit of the polymer comprises at least four carbon atoms and at least one carbon-carbon double bond, and a silane.

Glass fiber sizing compositions, sized glass fibers, and polyolefin composites

There is provided a curable composition comprising (A) a cyclic olefin; (B) a metathesis catalyst for polymerizing the cyclic olefin; (C) 0.1-30 wt. % of a compound comprising at least one vinyl group; and (D) 0.1-10 wt. % of a curing agent for compound (C), wherein the wt. % are relative to the total weight of the composition. The composition provides a desirable combination of workability, toughness and heat resistance. Also provided is a molded article comprising the composition and reinforcing fibers, and a method of manufacturing the same.

Curable composition and molded article comprising the composition

The present invention relates to a polycycloolefin (PCO) thermoset network assembly and a process for its preparation obtainable by polymerising a first reactive composition comprising a norbornene-type cycloolefin monomer in the presence of a Mo- or W-catalyst to obtain a PCO-Mo/W-network and polymerising a second reactive composition comprising a nor-bornene-type cycloolefin monomer in the presence of a Ru-catalyst on said PCO-Mo/W-network to obtain a PCO thermoset network assembly.
