Abstract: A process for the production of a nonaqueous stable emulsion feedstock comprising a rubber, a block copolymer having at least one component miscible with the rubber and at least one component miscible with the monomer, and at least two unsaturated organic monomers capable of free radical polymerization is disclosed. At least one of the monomers must be miscible with the rubber and the mixture of the monomers is substantially a nonsolvent for the rubber. The block copolymer maintains the rubber or rubber-rich particles in emulsified form within the mixture of monomers. In general, the process comprises (1) mixing the rubber, block copolymer and at least a portion of the rubber miscible monomers to form a first nonaqueous solution, (2) mixing the remaining monomers and the remaining portion of the rubber miscible monomers to form a second solution, and (3) combining the two solutions to form the nonaqueous stable emulsion feedstock.

Abstract: A method of grafting maleic anhydride or maleic anhydride/styrene onto a polyolefin, in particular polypropylene comprising mixing maleic anhydride or maleic anhydride-styrene/styrene homologue with the polyolefin in the presence of a catalyst having the formula: ##STR1## wherein X=S, O or N;R.sub.1 and R.sub.2 =an alkyl group, for example C.sub.1 -C.sub.14 or higher;R=H or ##STR2## wherein R.sub.3, R.sub.4 and R.sub.5 equal H, an alkyl group, (CH.sub.2).sub.n COOH, or mixtures thereof; andn=1 to about 6.

Abstract: The process for manufacturing polyamides, suitable for fibers, from an .alpha.,.omega.-dinitrile, and an .alpha.,.omega.-diamine in water in contact with a catalyst that is improved by (1) first, reacting the dinitrile and water in the presence of the catalyst at a temperature sufficient to cause substantial hydrolysis of the dinitrile and (2) subsequently adding the diamine to the reaction mixture of the dinitrile and water at a temperature sufficient to cause polymerization.
