Title:

NOVEL POLYACETAL &lpar CO&rpar POLYMERS

Document Type and Number:

WIPO Patent Application WO/2003/011930

Kind Code:

A1

Abstract:

Polymers which are liquid in spite of their being high−molecular substances, exhibit both high affinity for water and excellent heat resistance, and are suitable for heat media, lubricants, and so on. That is, polyacetal (co)polymers liquid at room temperature, which are produced by (co)polymerizing (A) 75 to 100 % by mole of 1,3−dioxolane with (B) 25 to 0 % by mole of trioxane and have total terminal group contents of 15 to 300 mmol&sol kg and terminal hemiformal group contents of 80 mmol&sol kg or below.
