Polyolefins ethylene

A series of compounded flame retardants, based on finely divided insoluble ammonium polyphosphate together with char-forming nitrogenous resins, has been developed for thermoplastics (52—58). These compounds are particularly useful as iatumescent flame-retardant additives for polyolefins, ethylene—vinyl acetate, and urethane elastomers (qv). The char-forming resin can be, for example, an ethyleneurea—formaldehyde condensation polymer, a hydroxyethylisocyanurate, or a piperazine—triazine resin. [Pg.476]

Ethylene/propylene co-polymers (usually called EPRs for ethylene-propylene rubbers, or EPMs for ethylene-propylene monomers) are amorphous polyolefins when the propylene content is in the range 30-70%. Despite the typical unreactivity of saturated polyolefins, ethylene-rich EP co-polymers can be made highly elastic by radical cross-linking, but in order to make the rubber vulcanizable , a diene (5-ethylidene-2-norbornene, 1,4-hexadiene, or dicyclopentadiene) is added, which leaves one unreacted double bond available for subsequent cross-linking. These latter materials are called EPDMs (for ethylene-propylene-diene monomers). [Pg.1045]

In 2003 Dow introduced three classes of compatibiliser, i.e., maleated polyolefins, ethylene-vinyl acetate and ethylene-ethyl acrylate copolymers, all imder the Amplify name. They were intended to improve the impact and viscosity characteristics of engineering thermoplastics and polyolefins for use in domestic appliance and automotive components, as well as for coatings and adhesives.

The packing material, polymeric film, polythene (polyolefins, ethylene copolymers, etc.) have received such a wide application, that neither human activity, nor, all the more, natural environment is capable to cope with the inflow of polymeric waste products. In this connection there appeared a necessity of manufacturing of polymeric materials capable of biodecomposition under the influence of the environment and microorganisms. [Pg.187]

Sedlar and co-workers [27] has described a gas chromatographic procedure, outlined below, for the determination of dilauryl p, P thiodipropionate antioxidant and its primary oxidation products in polyolefins, ethylene-vinyl acetate co-polymers, acrylonitrile-butadiene-styrene resins and high impact polystyrene. These workers examined the conditions under which di-lauryl-thiodipropionate and its oxidation products are hydrolysed, by 5 N methanolic potassium hydroxide at 80 °C, quantitatively to lauryl alcohol, thus making gas chromatographic determination possible. The method described next has the advantages of being rapid, accurate and simple. It has been applied successfully to the... [Pg.172]

Thin-layer liquid chromatography has been employed for the determination of alkylated cresols and amine antioxidants [102, 103] in polybutadiene, phenolic antioxidants in PE [104-106] and PP [106], dilauryl and distearyl thiodipropionate antioxidants in polyolefins, ethylene-vinyl acetate copolymer, acrylonitrile-styrene terpolymer and PS, UV absorbers and organotin stabilisers in polyolefins [102], and accelerators such as guanidines, thiazoles, thiurans, sulfenamides, diethiocarbamides, and morpholine disulfides in unvulcanised rubber compounds.

Blends based on halogen-containing polymers are also significant [30-32]. Those based on halo-genated polyolefin/ethylene interpolymer blends are claimed to be single-phase systems [32]. They are often used where solvent and fire resistance is important. PVC/nitrile rubber/dioctyl phthalate blends are used in similar applications and also in footwear [30-32]. [Pg.101]
