Aliphatic polyhalides

Alkyl halides 93. Aryl halides 93. Halogen-substituted aliphatic acids, aldehydes, ketones, ethers, alcohols and esters 94. Aliphatic polyhalides 95. Acid halides 96. 

Liquid polysulfides can also be prepared directly with thiol end groups by reacting a mixture of aliphatic di- and polyhalides with a mixture of sodium disulfide and sodium hydrogen sulfide [77]. Reaction polymeric disulfides with polymercaptans also leads to the formation of liquid polysulfides [37]. LP polymers with M in the range of 600 to 8000 are generally f eferred. The uncured LP polymers are soluble in toluene, benzene and chlorinated hydrocarbons such as ethylene chloride [17, 78]. LP polym like LP-31, LP-2, LP-32, LP-12, LP-3, LP-33, LP-5, LP-8, based on range of viscosities, molecular weights and functionalities, are available [17].
