Abstract
Abstract (Meth)-acrylic acid derivatives of tricyclodecanes of the formula ##STR1## in which R 1 and R 2 are identical or different and denote hydrogen, lower alkyl, lower alkoxy, halogen or trifluoromethyl and R 3 and R 4 are identical or different and represent the group ##STR2## wherein X denotes a divalent bridge member from the group ##STR3## and Y denotes a divalent bridge member from the group ##STR4## and wherein R 5 represents hydrogen or methyl and R 6 represents lower alkyl or phenyl, have been found. Dental compositions in which the present (meth)-acrylic acid derivatives of tricyclodecanes are used, exhibit considerably less polymerization shrinkage.
