Abstract
This composition, which is useful as a binder in the preparation of synthetic resin concretes or mortars, bonding primers or finishing coats, comprises (A) a system of monomers comprising: (a1) 50-90 parts of a dicyclopentenyloxyalkyl eater: ##STR1## where R=H or CH.sub.3 ; n=1 or 2; and R.sup.1 =C.sub.2 -C.sub.6 alkylene; (a2) 0-25 parts of at least one heavy (meth)acrylate giving a homopolymer with a Tg higher than that of a homopolymer of (a1); (a3) 0-25 parts of at least one heavy (meth)acrylate giving a homopolymer with a Tg lower than that of a homopolymer of (a1); (a4) 0-25 parts of at least one monomer containing at least two (meth)acrylic unsaturations; and (B) 5-30 parts of at least one poly(allyl glycidyl ether); and (C) an initiating system chosen from (C1) to (C4): (C1) 0.1-3 parts of at least one organic peroxide derived from a C.sub.3 -C.sub.18 hydrocarbon compound and 0.1-2 parts of at least one aromatic amine; (C2) 0.1-3 parts of at least one organic hydroperoxide derived from a C.sub.3 -C.sub.18, hydrocarbon compound and 0.0005-2 parts of at least one polyvalent metal salt; (C3): (C1) +0.0005-2 partsof at least one polyvalent metal salt; and (C4): (C1)+(C2), all t…
