MODIFIED DISULFIDE POLYMER COMPOSITION AND METHOD FOR MAKING SAME |
摘要 |
<p>A liquid polymer composition curable to a solid elastomer having good thermal stability which contains a mercaptan terminated disulfide polymer of the formula HS(RSS)mR'SH wherein R is -C2H4-O-CH2O-C2H4-; R' is a member selected from the group consisting of alkyl of from 2 to 12 carbon atoms; alkyl thioether of from 4 to 20 carbon atoms; alkyl ether of from 4 to 20 carbon atoms and one oxygen atom; alkyl ether of from 4 to 20 carbon atoms and from 2 to 4 oxygen atoms each of which is separated from the other by at least 2 carbon atoms, alicyclic of from 6 to 12 carbon atoms and aromatic lower alkyl; and the value of m is such that mercaptan terminated disulfide polymer has a molecular weight of between 1,000 to about 4,000. The method includes cleaving a polymer having disulfide linkages with an organic dimercaptan in the presence of an organic amine.</p> |
