| description | Radically polymerizable composition comprises: (A) more than 15 wt.% of an at least bifunctional oligomer capable of forming a homopolymer with a glass transition temperature (Tg) below 50 deg C and a copolymer with a Tg of 50 deg C or less; and (B) at least 15 wt.% of a hydrogen-bonding (meth)acrylic monomer. An Independent claim is also included for a product resulting from the thermal and/or photochemical polymerization of a composition as above.
The invention concerns a composition capable of free radical polymerization comprising: a first constituent A including at least an oligomer bearing at least two functions capable of free radical polymerization and whereof the homopolymer has a glass transition temperature (Tg) less than 50 DEG C, said constituent being capable of resulting by polymerization in a (co)polymer having a glass transition temperature (Tg) not higher than 50 DEG C, preferably not higher than 0 DEG C and more preferably still ranging between 50 DEG C and 10 DEG C, said oligomer representing more than 15 %, preferably less than 20 % of the total weight of polymerisable monomers present in the composition; and a second constituent B including at least a (meth)acrylic monomer bearing at least a H bond promoter group, said (meth)acrylic monomer representing at least 15 % of the total weight of the polymerisable monomers and oligomers present in the composition when said monomer is a methacrylic monomer and at least 35 % of the total weight of polymerisable monomers and oligomers present in the composition when said monomer is an acrylic monomer.
