초록

Modification of a starch hydrolyzed polyacrylonitrile graft copolymer with aluminum or with aluminum and a polyhydric alcohol.

대표청구항 ▼

1. A method for modifying a hydrolyzed starchpolyacrylonitrile or methacrylonitrile graft copolymer which comprises treating said copolymer in dry state with an aqueous source of aluminum ions. 2. A method in accordance with claim 1 wherein the copolymer is treated with aluminum at ambient temperature. 3. A method in accordance with claim 1 wherein the copolymer is treated with aluminum at an elevated temperature. 4. A method for modifying a hydrolyzed starch polyacrylonitrile or methacrylonitrile graft copolymer which comprises treating said compolymer in dry state with a mixture of a polyhydric alcohol and a source of aluminum ions. 5. A method in accordance with claim 4 wherein an aqueous mixture of a polyhydric alcohol and a source of aluminum ions is employed. 6. A method in accordance with claim 4 wherein the copolymer is treated with said mixture at ambient temperature. 7. A method in accordance with claim 4 wherein the copolymer is treated with said mixture at an elevated temperature.
