Abstract:
Water soluble dialkylaminoethyl vinyl ether interpolymers of the formula
AND SALTS THEREOF WHEREIN R1 and R2 are each selected from the group consisting of methyl, ethyl, or hydroxyethyl or taken together with the N atom to which they are attached a heterocyclic ring, X and Y are selected from vinyl monomers copolymerizable with said other monomers and wherein the proportions of a, b, c and d of said monomer units in said interpolymer calculated on the basis of weight percent of the interpolymer amount to 80-10 weight percent of a, 70-10 weight percent of b, 30-0 weight percent of c, and 20-0 weight percent of d. The interpolymers of the invention are useful as flocculants and retention aids.
Abstract:
AN EASILY PROCESSABLE RESIN COMPOSITION COMPRISING
(A) A NORMALLY DIFFICULTLY PROCESSABLE THERMOPLASTIC RESIN, OF THE TYPE OF VINYL CHLORIDE POLYMER AND THEIR CHLORINATION PRODUCTS; AND (B) IN AN AMOUNT SUFFICIENT TO EFFECT AN IMPROVEMENT IN THE PROCESSABILITY OF SAID NORMALLY DIFFICULTLY PROCESSABLE THERMOPLASTIC RESIN, A GRAFT COPOLYMER COMPRISING METHYL METHACRYLATE GRAFTED ONTO AN ALKYL VINYL ETHER BACKBONE POLYMER, THE METHYL METHACRYLATE UNITS BEING PRESENT IN AN AMOUNT OF 10-95% BY WEIGHT AND THE ALKYL VINYL ETHER BACKBONE POLYMER BEING PRESENT IN AN AMOUNT OF 5-90% BY WEIGHT BASED ON THE TOTAL WEIGHT OF THE GRAFTED COPOLYMER.
Abstract:
Oriented films of polymers of methyl vinyl ether and maleic anhydride are disclosed. Additionally, terpolymers of methyl vinyl ether, maleic anhydride and higher alkyl vinyl ethers are disclosed. The films can be uniaxially, biaxially, or multiaxially oriented.
Abstract:
POLYMERIZATION OF ACROLEIN IN PRESENCE OF 0.5 TO 9% BY WEIGHT BASED ON THE TOTAL REACTION MIXTURE-OF SODIUM SULFATE IN AQUEOUS SOLUTION WITH A PERSULFATE OR OTHER FREE RADICAL YIELDING POLYMERIZATION CATALYST.
Abstract:
PROCESS FOR INTERPOLYMERIZATION OF MALEIC ANHYDRIDE WITH ALKYL VINYL ETHERS IN THE PRESENCE OF AN ANTI-CLUMPING AGENT COMPRISING COPOLYMERS OF MALEIC ANHYDRIDE WITH HIGHER ALKYL VINYL ETHERS IN HIGH SOLIDS CONTENT WHEREBY THE INTERPOLYMER IS RECOVERED AS A FREE-FLOWING POWDER AFTER EVAPORATION OF THE SOLVENT AND IN WHICH THE ANTICLUMPING AGENT IS COMPATIBLE WITH THE LOWER ALKYL VINYL ETHER MALEIC ANHYDRIDE COPOLYMER AT SUBSTANTIALLY PH7 AND ABOVE EVEN AT THE BOILING POINT OF THE SOLUTION.
