##STR00001##

and a basic co-additive selected from alkali metal or alkaline metal salts of higher fatty acids are disclosed. Amounts of the chroman-based compound and the basic co-additive are selected to enhance processing stability of the polyolefin composition when subjected to extrusion, even in the absence of antistatic agents and organic phosphites and phosphonites. Masterbatch compositions of a first polyolefin, the chroman-based compound and the basic co-additive can be blended with a second polyolefin, identical to, or compatible with, the first polyolefin to form a stabilized polyolefin composition. Molded articles produced by molding the polyolefin compositions are also disclosed. R.sub.21, R.sub.22, R.sub.23, R.sub.24, R.sub.25, R.sub.26, and R.sub.27 are also described.

Described herein is a method of using glass fibers having a tensile strength according to DIN ISO 527-5 of 86.0 to 92.0 GPa, a tensile elastic modulus according to DIN ISO 527-5 of 2600 to 3200 MPa and a softening point according to DIN ISO 7884-1 of 900° C. to 950° C. the method including using the glass fibers to increase the weld seam strength of shaped articles made of molding materials including thermoplastic polyamides.

A novel reaction resin formulation having a significantly improved properties profile contains crosslinkers, monomers, urethane methacrylates, prepolymers, optional further auxiliaries, and a curing system containing permaleinates and a tertiary organic phosphite. The reaction resin formulation is useful for marking driving surfaces or coating surfaces. The reaction resins, above all based on a novel curing system, show an improved combination of higher long-term storage stability, improved toxicological profile, reduced curing time, a low yellowing tendency and a better colour fastness.

An object is to provide a cured product, for example, that is made with a curable resin composition containing a curable resin having a particular structure, a radical polymerization initiator, and a flame retardant and therefore is superior in flame retardancy, heat resistance (high glass transition temperature), and dielectric properties (low dielectric properties). Specifically, there are provided a curable resin represented by general formula (1) below and a curable resin composition containing this curable resin, a radical polymerization initiator (B), and a flame retardant (C). (In general formula (1) above, Y is a substituent represented by general formula (2) below, and the details of the substituents and the numbers of substituents presented in general formulae (1) and (2) above are as described in the text.)
