Use and Manufacturing
Use and Manufacturing:
Methods of Manufacturing

Polyvinylpyrrolidone is prepared by Reppe's process: 1,4-butanediol obtained in the Reppe butadiene synthesis is dehydrogenated over copper at 200 deg C forming gamma-butyrolactone; reaction with ammonia yields pyrrolidone. Subsequent treatment with acetylene gives the vinyl pyrrolidone monomer.
Produced commercially as a series of products having mean mol wt ranging from about 10,000 to 700,000.
Polymerization ... By heating in presence of H2O2 & NH3.

Usage:
Clarifying agent in wines, beer, fruit juice and as a dispersing and suspending agent in pharmaceutic aid.
Biomedical Effects and Toxicity
Therapeutic Uses:
Pharmaceutic Aids; Plasma Substitutes
CLINICAL INDICATIONS: ...FOR ALL PATHOLOGICAL CONDITIONS WHERE THERE IS DECR IN MASS OF LIQ BLOOD: SHOCK STATE... HEMORRHAGE...SERIOUS BURNS. ANTHREPSIA & NEURO-TOXICOSES OF INFANTS.
...HAS BEEN USED IN A...SERIES OF PATIENTS TO REPLACE THE AQ HUMOR AFTER EXTRACTION OF CATARACTS, CORNEAL TRANSPLANTS, & ANTIGLAUCOMA OPERATIONS.
Biomedical Effects and Toxicity:
WHEN GIVEN PARENTERALLY, UNEXCRETED PARTICLES ARE PHAGOCYTIZED BY CELLS OF RETICULOENDOTHELIAL SYSTEM & DEPOSITED IN STORAGE SITES IN LIVER, SPLEEN, LUNG, BONE MARROW...
...30-40% OF SUBTOSAN PASSES INTO THE URINE IN THE FIRST 24 HR & ABOUT 50% IN THE FIRST 2 DAYS. ...SMALLEST MOLECULES ARE...FIRST & MOST RAPIDLY EXCRETED. IT TAKES 10 DAYS AFTER PERFUSION FOR 80% OF AMT INJECTED TO BE ELIMINATED.
INTERMEDIATE MOLECULR WT PARTICLES MAY BE SLOWLY EXCRETED OVER SEVERAL MONTHS TO A YR.
IN GROUPS OF RATS FED DIETS CONTAINING 1 & 10% PVP (MOLECULAR WEIGHT 38,000) FOR 2 YEARS...THERE WAS NO EVIDENCE THAT PVP WAS ABSORBED FROM THE INTESTINAL TRACT.
THE RETENTION OF PVP IN THE BODY IS PROPORTIONAL TO ITS MOLECULAR SIZE, SINCE ONLY THAT OF LOW MOLECULAR WEIGHT CAN BE EXCRETED. THE RETICULOENDOTHELIAL SYSTEM RETAINS PVP WITH A MOLECULAR WEIGHT IN EXCESS OF 110,000.
