Abstract
PURPOSE: To prepare a wax having excellent compatibility and dispersibility in solvents, vehicles, resins, etc., by feeding an unsaturated epoxy monomer having a special structure to a polyolefin at a specific ratio in the absence of a solvent, thereby grafting the monomer homogeneously to the polymer.
CONSTITUTION: (A) A polyolefin (pref. the molecular weight is 400W9,000 and the ethylene content is ≥70mol%) is grafted with (B) an unsaturated epoxy monomer expressed by the formula (R is polymerizable ethylenic unsaturated bond-containing hydrocarbon group; R1 and R2 are H, 1W4C alkyl or R1 and R2 together form a 2W3C alkylene; n and m are 0 or 1) (pref. allyl glycidyl ether etc.) in the absence of a solvent preferably at 100W200°C in the presence of a radical initiator with feeding (B) at a rate of 10-5W10-2 (pref. 4×10-5W10-3) mol/hr per 1g of (A). The epoxy equivalent is preferably adjusted to 200W100,000.
