Abstract
Described are high-strength materials which are degradable and resorbable in the human and animal organisms and shaped articles manufactured therefrom, such as implants, based on cured (meth)acrylic acid esters of polyfunctionally hydroxyl-terminated oligomers of lower hydroxycarboxylic acids {polyfunctional (meth)acrylic acid esters}. The invention is characterized in that said materials and/or shaped articles have been three-dimensionally cross-linked by radiation-curing and/or any other, however boron-free, free radical-initiated polymerization of the polyfunctional (meth)acrylic acid esters and exhibit a tensile strength under standard conditions of at least 10 N/mm.sup.2.
