Disclosed is a method for preparing an article comprising 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 comprises 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 _(1000) at 30C of more than 9 sec. Articles such as pipe line field joint or a protective element for a concrete tunnel lining element can be obtained with the method.


There is provided a curable composition comprising (A) a cyclic olefin; (B) a metathesis catalyst for polymerizing the cyclic olefin; (C) a radical polymerization curable compound; and (D) a curing system for compound (C), wherein the curing system comprises a curing agent selected such that its half life t_(1/2CT) at the curing temperature and the time t_(c80) needed to complete at least 80% of the cyclic olefin polymerization reaction at the curing temperature (CT) satisfy 2.5 times t_(c80) < t_(1/2CT) < 1000 times t_(c80). The composition when used as a polymer matrix material in a composite retains a desirable combination of properties, in particular a good bonding with the reinforcing fibers. Also provided is a molded article comprising the composition and reinforcing fibers, and a method of manufacturing the same.


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.


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.


The invention relates to a process for the preparation of bidentate Schiff base catalysts containing a salicylaldimine-type ligand.


The present invention relates to a catalytic complex for olefin metathesis reactions, to a process for its preparation and to its use in olefin metathesis reactions, particularly in ring opening metathesis polymerisation (ROMP) reactions.
