    摘要： Biodegradable anionic polymers are disclosed which include recurring polymeric subunits preferably made up of vinylic and dicarboxylic monomers such as vinyl acetate or vinyl alcohol and maleic anhydride, itaconic anhydride or citraconic anhydride, or combinations thereof. Free radical polymerization is used in the synthesis of the polymers, which are then hydrolyzed to replace ester groups with alcohol groups. The polymers may be complexed with ions and/or mixed with fertilizers or seed to yield agriculturally useful compositions. The preferred products of the invention may be applied foliarly, to seeds, to fertilizer, or to the earth adjacent growing plants in order to enhance nutrient uptake by the plants.

    摘要： In the first aspect of the present invention, there is disclosed a method for producing a copolymer of an alkyl vinyl ether and maleic anhydride which comprises removing an organic solvent used in a reaction under a temperature so that a slurry state can be maintained. According to the first aspect, such a copolymer of the alkyl vinyl ether and maleic anhydride which contains a little amount of the solvent remaining therein as disclosed in the second aspect of the present invention, can be obtained. Further, it can be avoided that a specific viscosity of the copolymer of the alkyl vinyl ether and maleic anhydride is lowered, by means of a method for producing a copolymer of alkyl vinyl ether and maleic anhydride which comprises shielding oxygen in a polymerization, as disclosed in the third aspect of the present invention.

    摘要： The present invention is a method of preparing an acrylic copolymer having an acid anhydride group with a number average molecular weight of 1,500-5,000 comprising; polymerizing a monomer mixture of a radical polymerizable monomer having an acid anhydride group and another radical polymerizable monomer at a temperature of 150null C. or higher by using a radical initiator, wherein the concentration of the monomer mixture is 50-75 wt %. This method can provide an acrylic copolymer having an acid anhydride group with a relatively low molecular weight that does not cause the problem of yellowing after baking when used in an acid/epoxy curing type clear paint, by means of high temperature polymerization without the use of a large amount of an expensive initiator.
