PROBLEM TO BE SOLVED: To obtain an allyl compound suitable as a raw material for plasticizers and synthetic resins having amphipathic effect, namely, both solubility to water and dispersibility, such as heat-resistant resins, and useful for a paper manufacturing additive having a combination of paper strengthening ability and sizing performance. SOLUTION: This compound, an alkenylsuccinic half ester compound of formula I (R1 and R2 are each H, a 1-23C alkyl, etc.; R1 +R2 is of 3-46C; R3 is H or methyl; M is H, an alkali metal, etc.) or formula II, is obtained by reaction of an alkenylsuccinic anhydride (e.g. derived from a 6-49Cα-olefin such as 1-hexene) with an equivalent of an alcohol or methallyl alcohol in a solventless or organic solvent system under normal or higher pressures pref. at 10-100 deg.C for 30min to 20h. Besides, 10.0-90.0wt.% of the compound(s) of formula I and/or formula II is copolymerized with 10.0-99.9wt.% of a vinyl compound to obtain a polymeric compound bearing this compound on the side chain.
