摘要： The invention provides a making method of modified polyvinyl alcohol embolic microspheres. First, polyvinyl alcohol dimethyl sulfoxide solution is added to acryloyl chloride dichloromethane solution for reaction, then taurine solution is added to the above solution for further reaction, so that functional groups are introduced into the side chains of polyvinyl alcohol, then blank microspheres are prepared by suspension crosslinking method, and finally, drug-loaded modified polyvinyl alcohol embolic microspheres are prepared. The invention aims at improving the drug loading rate and drug loading speed of the microspheres. Through modification, the crystallinity of polyvinyl alcohol is weakened, the swelling in water is accelerated, and the application effect of the microspheres is improved.

摘要： A grafted polyvinyl alcohol polymer includes a polyvinyl alcohol main chain and a plurality of side chains grafted to the polyvinyl alcohol main chain. One or more of the side chains from the plurality of side chains include one or more units selected from: an aliphatic carboxylic acid, an aliphatic amide, an amino alkyl (meth)acrylate, a hydroxylated alkyl (meth)acrylate, or any combinations thereof. The grafted polyvinyl alcohol polymer can be included in a formulation that also includes water, and the formulation can be used as an adhesive in a creping process.
