ABSTRACT:
A shaped medical device article prepared from a polymer melt composition comprising a polymer ester, a transesterification catalyst, and a tri- or tetraalkoxy silane, by forming and solidifying said composition, and after solidification, subjecting the composition to reaction conditions to effect hydrolysis at least some alkoxysilyl groups remaining in the composition to form silanol groups and to effect condensation of said silanol groups to form a ceramic network. The polymer ester may be a vinyl ester homopolymer or copolymer, or a polymer having ester groups in the backbone thereof.
