Described herein are methods for preparing bioabsorbable polymerization products having interconnecting pore structure by polymerizing compositions containing ethylene glycol- or glycero-oligoester(meth)acrylates monomers and, optionally, other components. The polymerization products are particularly useful for dental lacquers, dental inlays and shaped articles which are bioabsorbable and exhibit an interconnecting pore structure.

[ What is claimed is:] [1.]1. A process for the preparation of an implantable shaped article comprised of a bioabsorbable polymerization product having an interconnecting pore system which comprises polymerizing a composition contained in a porous matrix in the form of the shaped article by means of electromagnetic radiation of less than 10 nm and dissolving away the porous matrix to provide the shaped article of a bioabsorbable polymerization product having an interconnecting pore system, said composition comprising 10 to 80% by weight of hydroxyapatite and at least one monomeric compound of the formula IR.sup.1, R.sup.2 and R.sup.3 in each case independently of one another are --(CH.sub.2)--, --CH(CH.sub.3)--, --CH.sub.2 --CH.sub.2 --, --CH.sub.2 --CH.sub.2 --CH.sub.2 --, --CH(CH.sub.3)--CH.sub.2 --, --CH.sub.2 --CH(CH.sub.3)--or 1,2-, 1,3- or 1,4-phenylene,R.sup.4, R.sup.4' and R.sup.4" in each case independently of one another are H or CH.sub.3,i, j and k in each case independently of one another are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10, provided that i, j and k are not simultaneously 0,n is 0 or 1.
