Zusammenfassung:	1,177,827. Polythioether diols. SOC. NATIONALE DES PETROLES D'AQUITAINE. 2 May, 1967 [9 May, 1966], No. 20366/67. Heading C2C. A process for the production of polythioether diols of formula HO(CH 2 S) m CH 2 OH comprises the reaction between a dithiol of formula HS(CH 2 S) n H and formaldehyde at a temperature of 0-100 C. in the absence of a catalyst. In the above formulµ w=n+1=2 to 31.
