A thermoplastic synthetic resin such as polyethylene or ethylene-vinyl acetate copolymer resin containing 0.1 to 10 wt. % of a specific additive selected from specific classes of compounds, namely saturated higher fatty acid amidas, saturated higher aliphatic amines and complete esters of saturated higher fatty acids is found to be very suitable for production of expanded articles and can be easily formed into expanded articles with little shrinkage after expansion, free from creases on the surface or cracks on the cell walls, and having excellent characteristics such as good closed cellular characteristic, high compressive strength, low density. etc.

Structured particle latexes are prepared by emulsion polymerizing monomeric materials in aqueous media in one or more stages wherein in at least one of the stages a reactive polymeric surfactant is used. The resulting latex contains nonionic particles to which are bound the reactive polymeric surfactant which forms a layer containing stabilizing anionic or cationic groups such as sulfonic, sulfonium, quaternary ammonium, or sulfonate groups chemically bound at or near the surface of the polymer particles dispersed in the aqueous media. These latexes are particu- lady suitable for beater additives, coatings and composite binders.
This invention relates to a stable water-in-oil emulsion which contains a water soluble vinyl addition of polymers or copolymers. One or more water soluble water-in-oil emulsifying agents containing a surfactant and system which comprises a mixture of one or more hydrophillic surfactants.
