Composition based on dicyclopentadienyloxy ester of (meth)acrylic acid and their use in the field of construction

摘要

Compsn. for use as binder in prepn. of concrete and mortar based on synthetic resins or as coupling primer or finishing coating, comprises: (A) a monomer system of (a1) 50-90 wt. parts dicyclopentenyloxyalkyl ester (I): R = H or Me; n = 1 or 2;R1 = 2-5C alkylene; (a2) 0-25 wt. parts at least one heavy (meth)acrylate producing a homopolymer with glass transition temp. (Tg) above that of (I) homopolymer; (a3) 0-25 wt. parts at least one heavy (meth)acrylate producing a homopolymer with Tg below that of (I) homopolymer; (a4) 0-25 wt. parts at least one monomer having at least two (meth)acrylic unsaturations; (B) 5-20 wt. parts at least one (poly)allyl glycidyl ether (II) and (C) an initiation system of (c1) 0.1-3 wt. parts organic peroxide derived from 1 3-18C hydrocarbon and 0.1-2 wt. parts at least one aromatic amine, opt. also 0.0005-2 wt. parts at least one polyvalent metal salt and/or (c2) 0.1-3 wt. parts similar organic hydroperoxide plus 0.0005-2 wt. parts polyvalent metal salt. Also new are synthetic resin concretes and mortars, coupling primers and finishing coatings contg. the new compsn.
