Abstract:
A composition intended to be used as binder in the preparation of synthetic resin concretes or mortars or as bonding primer or as finishing coat, formed from(A) a system of monomers comprising:(a1) 50 to 90 parts by weight of a dicyclopentenyloxyalkyl ester of formula (I): ##STR5##in whichR represents H or CH.sub.3 ;n has the value 1 or 2; andR.sup.1 represents a C.sub.2 -C.sub.6 alkylene group;(a2) 0 to 25 parts by weight of at least one (meth)acrylate giving a homopolymer in which the glass transition temperature is greater than the glass transition temperature of a homopolymer of the ester (a1);(a3) 0 to 25 parts by weight of at least one (meth)acrylate giving a homopolymer in which the glass transition temperature is lower than the glass transition temperature of a homopolymer of the ester (a1);(a4) 0 to 25 parts by weight of at least one monomer having at least two (meth)acrylic unsaturations; and(B) 5 to 30 parts by weight of at least one poly(allyl glycidyl ether).; and(C) an initiating system:(C1) 0.1 to 3 parts by weight of at least one organic peroxide derived from a C.sub.3 -C.sub.18 hydrocarbon compound and 0.1 to 2 parts by weight of at least one aromatic amine;(C2) 0.1 to 3 parts by weight of at least one organic hydroperoxide derived from a C.sub.3 -C.sub.18 hydrocarbon compound and 0.0005 to 2 parts by weight of at least one polyvalent metal salt;(C3) a mixture of (C1) and of 0.0005 to 2 parts by weight of at least one polyvalent metal salt; or(C4) a mixture of (C1) and (C2), all the amounts being given per 100 parts by weight of (A)+(B).
