ABSTRACT:
A radically polymerizable composition comprising:a first component A comprising at least an oligomer having at least two radically polymerizable functions and the homopolymer of which has a glass transition temperature (Tg) lower than 50° C., such a component being able to result through polymerization in a (co)polymer having a glass transition temperature (Tg) equal to or lower than 50° C., preferably equal to or lower than 0° C. and more preferably ranging from −50° C. to −10 C., said oligomer accounting for more than 15%, preferably at least 20% of the total weight of the polymerizable monomers present in the composition; anda second component B comprising at least a (meth)acrylic monomer having at least one H link promoting group, such a (meth)acrylic monomer accounting for at least 15% of the total weight of the polymerizable monomers and oligomers present in the composition when such a monomer is a methacrylic monomer and at least 35% of the total weight of such polymerizable monomers and oligomers present in the composition when such a monomer is an acrylic monomer.
