OXAZOLINE-MODIFIED POLYETHYLENE RESIN AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide an oxazoline-modified polyethylene resin having excellent dispersion stability in a nitrogen-containing solvent and high compatibility and adhesivity to other materials and provide its production process. SOLUTION: The objective oxazoline-modified polyethylene resin contains a unit expressed by general formula (I) and a unit expressed by general formula (II) (R1 is H or methyl; R2 is a bivalent organic group having 2C main chain and formed after the ring-opening of oxazoline group by reacting with active hydrogen; R3 is a univalent organic group consisting of a monooxazoline compound residue). The oxazoline-modified polyethylene resin can be produced by reacting (A) a polyethylene resin having carboxyl group with (B) a monooxazoline compound at a ratio of <1 equivalent of the oxazoline group in the component B based on 1 equivalent of the carboxyl group in the component A.
