A procedure for preparing a Polymer functionalized with Starch Graft Polyacrylamide

摘要

Method for the preparation of Polymers and functionalized with Polyacrylamide grafted Starch, soluble in water, which has applications as an additive for paper Wet Strength.Comprises the polymerization reaction of Enzyme converted Starch with acrylamide and degraded in the presence of a Free radical polymerization initiator, for producing a Polymer comprising a Main chain and Starch Graft PolyacrylamideThat is at least 5% Polyacrylamide polymer functionalized substituents; and dichbo derived from one or more materials that contain two or more units of aldehyde, such as GLUTARALDEHYDE or aldehydes Glyoxal, CYANURIC ACID, enough so that the ratio of Polymer Or substituents is 1: 1 to 1: 20.
