摘要:
A method for treating beverages containing turbidity procursors and/or enzymes is described. The technique involves contacting the beverages with a diol or dicarboxylic acid polycondensate at a temperature ranging from 28.4.degree. to 176.degree. F., thereby resulting in separation of deleterious substance. The colloidal and taste qualities of the resultant beverages is thereby enhanced.
摘要:
A method is described for the anionic polymerization and copolymerization of .omega.-aminoacid lactams. This end is attained at elevated temperatures in the presence of a polymerization initiator of the formulaMeZX.sub.m L.sub.nwherein Me is an alkali metal, Z is boron or aluminum, X is an alkoxy group and L is an organic residue derived from a lactam and being of the formula ##STR1## wherein a is an integer in the range 3-11, m is an integer in the range of 0-3, (m+n) is 4 and n is (4-m).
摘要:
A method for the anionic polymerization of unsaturated monomers involves effecting reaction in the presence of an organic derivative of a metal alumina hydride in an amount ranging from 0.01 to 5.0 mol percent based upon the amount of unsaturated monomer.
