Beschreibung
Zusammenfassung:	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.
