    Abstract: REACTIVE HYDROXYL GROUP-CONTAINING VINYL CHLORIDE TERPOLYMERS HAVING THE FOLLOWING FORMULA:

    -(CH2-CH(-O-R))X-(CH2-CH(-CL))Y-(CH(-R")-C(-R'')(-R"''))Z-

    WHEREIN R REPRESENTS AN ALKYL GROUP WHAVING FROM 1 TO 18 CARBON ATOMS, R'' REPRESENTS HYDROGEN OR METHYL, R" REPRESENTS HYDROGEN, HYDROXYALKYL OR HYDROXYALKYL CARBALKOXY, AND R$ REPRESENTS HYDROXY, HYDROXYALKYL OR HYDROXYALKYL CARBALKOXY, X REPRESENTS FROM ABOUT 50 TO ABOUT 98 MOLE PERCENT, Y REPRESENTS FROM ABOUT 1 TO ABOUT 40 MOLE PERCENT AND Z REPRESENTS FROM ABOUT 1 TO ABOUT 10 MOLE PERCENT. THE METHOD OF PREPARING THE NOVEL TERPOLYMERS BY COPOLYMERING CINYL CHLORIDE, AN ALKYL VINYL ETHER AND A POLYMERIZABLE HYDROXYLE GROUP-CONTAINING MONOMER IN THE PRESENCE OF A FREE RADICAL CATALYST IS ALSO DISCLOSED.

    Abstract: Phenolic complexes of water-insoluble but water-swellable crosslinked N-vinyllactam or N-alkyl-N-vinylamide polymers in the form of porous beads or granules and a process of preparing same. The complexes are particularly suited for use in situations wherein phenolic materials in limited quantities are desired such as, for example, in canisters or columns which are used to treat liquids or water. The novel complexes are prepared by adsorbing a phenolic material onto the porous granular or porous bead-like crosslinked N-vinyllactam or N-alkyl-N-vinylamide polymers.

    Abstract: Beverages such as juices, vinegars, beers and wines are clarified and rendered haze-free by contacting the beverages with water-insoluble, water-swellable, crosslinked N-vinyllactam or Nalkyl-N-vinylamide polymers in the form of porous granules or beads. The granules or beads when spent are regenerated by an aqueous alkaline treatment.
