Abstract

PURPOSE: To prepare a modified liquid polyisoprene rubber useful for solventless adhesives, etc. and having improved compatibility with resins, in high productivity, by reacting a liquid polyisoprene having a specific molecular weight and cis- 1,4 bond content with maleic anhydride in the presence of a phenol compound.
CONSTITUTION: A modified liquid rubber is prepared by reacting (A) a liquid polyisoprene rubber having a molecular weight of 8,000W10,000 and a cis-1,4- bond content of ≥70% with (B) maleic anhydride in the presence of (C) a phenol derivative (e.g. 2,6-di-t-butyl-4-methylphenol,etc.) at 120W250°C for 0.5W24hr.
EFFECT: Addition of (C) as an antioxidant suppresses the degradation of (A) at high reaction temperatures and ensures 100% of the conversion of (B).
