THERMOPLASTIC POLYESTER RESINS THE PRODUCTION THEREOF AND ORTHOPAEDIC CAST MATERIAL PRODUCED THEREFROM |
摘要 |
<p>New thermoplastic polyester resins having a low melting point which are useful as a molding material, especially as an orthopedic cast material; said resin having the formula (I): [A]1[B]m[C]n (I) where A denotes a residue of a straight or branched aliphatic dicarboxylic acid having 4 to 12 or 36 carbon atoms; B denotes a residue of a straight or branched aliphatic diol having 2 to 18 carbon atoms; C denotes a residue of 6-hydroxycaproic acid; these residues are linked through the ester bond and distributed randomly and/or in block in the molecule; 1, m, and n each has a value greater than 0; the residue of the 6-hydroxycaproic acid is 60 to 98 wt % and the sum of the residues of the aliphatic dicarboxylic acid and aliphatic diol is 40 to 2 wt %; the residue of the aliphatic dicarboxylic acid and the residue of the aliphatic diol are present in equimolar amount; and having a number-average molecular weight of 5,000 to 200,000.</p> |
