    摘要： SULFONATED BUTYL RUBBER CONTAINING GREATER THAN 0.5 MOLE PERCENT SO3H IS EMULSIFIED BY DISSOLVING THE ACID FORM OF THE POLYMER IN A SUITABLE SOLVENT INCORPORATING INTO THE SOLVENT RUBBER CEMENT ABOUT 5 TO 30 WT. PERCENT OF A POLAR COSOLVENT AND USING AS EMULSIFIERS NONIONIC EMULSIFIERS AT LEAST ONE OF WHICH IS AN ETHOXYLATED C8-C12 ALKYL PHENOL. IN A PREFERRED EMBODIMENT, AT LEAST ONE EMULSIFIER IS A WATER DISPERSIBLE OR WATER SOLUBLE EMULSIFIER AND IS DISPERSED IN THE WATER INTO WHICH THE CEMENT IS TO BE DISPERSED. THE ORGANIC AND POLAR SOLVENTS MAY BE STRIPPED FROM THE EMULSION ALONG WITH EXCESS WATER TO FORM LATICES SUITABLE FOR USE AS COATINGS AND FILM FORMERS.

    摘要： Novel flame retardant compositions of matter comprise a mixture of a polymeric material and a polyhalo-substituted polyhydropolycyclicdicarboxylic acid or anhydride thereof. These novel compositions of matter may be exemplified by a mixture of polypropylene and 5,6,7,8,9,9-hexachloro-6,7-dibromomethylene1,2,3,4,4a,5,8,8a-methano-2,3 -naphthalenedicarboxylic anhydride.

    摘要： A SELF-EXTINGUISHING POLYMER COMPOSITION IN LATEX FORM HAS BEEN PREPARED BY THE ADDING FROM 1 TO 10 PARTS BY WEIGHT OF TRIS(2,3-DIBROMOPROPYL) PHOSPHATE IN COMBINATION WITH A SYNERGISTIC AMOUNT (0.5 TO 3.0 PARTS BY WEIGHT) OF A SALT SELECTED FROM THE GROUP CONSISTING OF MONOAMMONIUM PHOSPHATE, DIAMMONIUM PHOSPHATE AND TRIAMMONIUM PHOSPHATE, TO A TERPOLYMER COMPRISING 2070 PARTS BY WEIGHT OF AN ARYL VINYL MONOMER AND 30-80 PARTS BY WEIGHT OF A CONJUGATED DIOLEFIN, AND 0.5-10 PARTS BY WEIGHT OF AN A,B-ETHYLENICALLY UNSATUARTED CARBOXYLIC ACID. IF DESIRED, A PORTION OF THE AMMONIUM SALT MAY BE ADDED TO THE LATEX DURING POLYMERIZATION AS WELL AS AFTER THE POLYMERIZATION.

    摘要： THERE IS DISCLOSED A PROCESS FOR AGGLOMERATING LATICES OF A POLYMER TO PROVIDE LARGER PARTICLES. AN ACID ANHYDRIDE IS ADMIXED WITH AN AQUEOUS LATEX OF A POLYMER WHICH CONTAINS AN ORGANIC ACID SALT EMULSIGYING AGENT FOLTHE LATEX AND THE ADMIXTURE IS ALLOWED TO STAND FOR A PERIOD SUFFICIENT TO HYDROLYZE THE ACID ANHYDRIDE AND PRODUCE AGGLOMERATION OF THE PLYMER PARTICLES. THEREAFTER, THE LATEX IS STABILIZED WITH EMULSIFYING AGENT.
