Ethylene-methyl acrylate rubbers

The ethylene-methyl acrylate rubbers were introduced in 1975 (Vamac—Du Pont) and are prepared from ethylene, methyl acrylate and a small amount of a third monomer to provide a cure site. The polymer is said to have the following structure ... [Pg.341]

A terpolymer rubber was introduced by Du Pont in 1975 (Vamac). This is based on ethylene, methyl acrylate and a third, undisclosed, monomer containing carboxylic acid groups to act as the cure site (see Section 11.9). [Pg.277]

More recently, in 1975, Du Pont introduced a terpolymer (Vamac) based on ethylene, methyl acrylate and a third monomer of undisclosed composition which contained a carboxylic acid group to provide a cure site for use with peroxides or amines. Both types of rubber exhibit good heat, oxygen and ozone resistance. [Pg.301]

An example of this improvement in toughness can be demonstrated by the addition of Vamac B-124, an ethylene/methyl acrylate copolymer from DuPont, to ethyl cyanoacrylate [24-26]. Three model instant adhesive formulations, a control without any polymeric additive (A), a formulation with poly(methyl methacrylate) (PMMA) (B), and a formulation with Vamac B-124 (C), are shown in Table 4. The formulation with PMMA, a thermoplastic which is added to modify viscosity, was included to determine if the addition of any polymer, not only rubbers, could improve the toughness properties of an alkyl cyanoacrylate instant adhesive. To demonstrate an improvement in toughness, the three formulations were tested for impact strength, 180° peel strength, and lapshear adhesive strength on steel specimens, before and after thermal exposure at 121°C. [Pg.857]

Polymers Characterized by HT-GPC A number of polymers can be characterized by GPC in 1,2,4-trichlorobenzene at an elevated temperature polyethylene, polypropylene, poly(ethylene-vinyl acetate), poly(ethylene-methyl acrylate), polyethylene propylene diamine rubber, different types of butyl rubber, and poly(phenylene oxide). In Table 17.3 are presented some common polymers, as well... [Pg.360]

Ethylene-Methyl Acrylate (EMA) Copolymers. EMA copolymers are often blown into film with very rubbery mechanical properties and outstanding dart-drop impact strength. The latex-rubber-hke properties of EMA film lend to its use in disposable gloves and medical devices without the associated hazards to people with allergies to latex rubber. Due to their adhesive properties, EMA copolymers, like their EAA and EEA counter-... [Pg.84]

Thermoplastic polyolefin (TPO) elastomers are typically composed of ethylene propylene rubber (EPR) or ethylene propylene diene M (EPDM) as the elastomeric segment and polypropylene thermoplastic segment. LDPE, HDPE, and LLDPE copolymers ethylene vinyl acetate (EVA), ethylene ethylacrylate (EEA), ethylene, methyl-acrylate (EMA) and polybutene-1 can be used in TPOs. Hydrogenation of polyisoprene can yield ethylene propylene copolymers, and hydrogenation of 1,4- and 1,2-stereoisomers of S-B-S yields ethylene butylene copolymers. ... [Pg.197]
