ABSTRACT OF THE DISCLOSURE The invention described herein provides a modified inorganic polymer represented by the formula: Image wherein P is an inorganic polymer linked to the 3' or 5' -0- of the nucleoside through a base hydrolyzable covalent bond; R is H or a blocking group; R1 is a hydrocarbyl radical containing up to 10 carbons; each B is a nucleoside or deoxy- nucleoside base; and each A is H or OR. Also provided by the invention as disclosed is a process for production of oligonucleotides which comprises the step of condensing the 3' -OH or 5' -OH group of a nucleoside or oligonucleotide covalently linked to an inorganic polymer by a coupling agent through the 5'-0- or 3' -0-, respectively, of said nucleoside or oligonucleotide with a phosphite compound of the formula: Image wherein R is a blocking group; B is a nucleoside or deoxy- nucleoside base; A is H or OR; R1 is lower alkyl; and X is C1 or Br, or a secondary amino group. The modified inorganic polymers are useful as supports for the synthesis of polynucleosides such as DNA and RNA, and also polypeptides.
