Appeal No. 96-2432
Application No. 08/066,087
present application, stand withdrawn from consideration.
Claim 21 is illustrative:
21. A composition of matter useful as a high-strength
material which is degradable and resorbable in the human
and animal organisms comprising cured (meth)acrylic acid
esters of polyfunctionally hydroxyl-terminated oligomers
of lower hydroxycarboxylic acids, wherein said
(meth)acrylic acid esters of polyfunctionally hydroxyl-
terminated oligomers of lower hydroxycarboxylic acids
have been prepared under solvent-free conditions in the
steps of the production of the oligomer(s), the
conversion thereof to the poly-functional (meth)acrylic
acid esters and the curing-shaping thereof, and three-
dimensionally cross-linked by boron-free, free radical-
initiated polymerization and exhibit a tensile strength
of at least 10N/mm .2
In the rejection of the appealed claims, the examiner
relies upon the following reference:
Ritter 4,731,425 Mar. 15, 1988
Appellant's claimed invention is directed to cured
(meth)acrylic acid esters of polyfunctionally hydroxyl-
terminated oligomers of lower hydroxycarboxylic acids that
have been prepared under solvent-free conditions. The cured
esters exhibit a tensile strength of at least 10N/mm . The2
cured esters of the present invention find utility as high-
strength materials that are degradable and resorbable in human
and animal organisms such that they can be used as pins for
the fixation of bone fragments.
