Abstract:
A process for preparing a non-toxic resin from a composition comprising a monomer, oligomer and/or polymer, wherein said monomer, oligomer and/or polymer contains organofunctional groups and can be crosslinked under irradiation in the presence of an initiator system, wherein the initiator system is an onium salt whose cationic structure is of the formula:[(CH(CH.sub.3).sub.2 -.phi.-)-I--(--R.sup.1)].sup.+ (I)in which the symbol R.sup.1 represents a radical -.phi.-R.sup.2, R.sup.2 being a linear or branched alkyl radical comprising from 1 to 10 carbon atoms, and .phi. represents a phenyl group, said process comprising the following steps:a) mixing molecules of said monomer, oligomer and/or polymer with said initiator system to obtain a mixture; andb) irradiating the mixture to obtain said non-toxic resin.
