Methyl methacrylate methylacrylate

The action of sulphuric acid alone upon acetone cyanohydrin affords a-methylacrylic acid. The methyl methacrylate polymers are the nearest approach to an organic glass so far developed, and are marketed as Perspex (sheet or rod) or Dialcon (powder) in Great Britain and as Plexiglass and Luciie in the U.S.A. They are readily depolymerised to the monomers upon distillation. The constitution of methyl methacrylate polymer has been given as ... 

Acryhc stmctural adhesives have been modified by elastomers in order to obtain a phase-separated, toughened system. A significant contribution in this technology has been made in which acryhc adhesives were modified by the addition of chlorosulfonated polyethylene to obtain a phase-separated stmctural adhesive (11). Such adhesives also contain methyl methacrylate, glacial methacrylic acid, and cross-linkers such as ethylene glycol dimethacrylate [97-90-5]. The polymerization initiation system, which includes cumene hydroperoxide, N,1S7-dimethyl- -toluidine, and saccharin, can be apphed to the adherend surface as a primer, or it can be formulated as the second part of a two-part adhesive. Modification of cyanoacrylates using elastomers has also been attempted copolymers of acrylonitrile, butadiene, and styrene ethylene copolymers with methylacrylate or copolymers of methacrylates with butadiene and styrene have been used. However, because of the extreme reactivity of the monomer, modification of cyanoacrylate adhesives is very difficult and material purity is essential in order to be able to modify the cyanoacrylate without causing premature reaction. 

Besides the MBS materials, related terpolymers have been prepared. These include materials prepared by terpolymerising methyl methacrylate, acrylonitrile and styrene in the presence of polybutadiene (Toyolac, Hamano 500) methyl methacrylate, acrylonitrile and styrene in the presence of a butadiene-methyl methacrylate copolymer (XT Resin), and methylacrylate, styrene and acrylonitrile on to a butadiene-styrene copolymer.

A number of polymer latices falling into this category have been described in the literature bot they are still relatively novel and have not received the extensive attention given to the more conventional latices. Probably the systems of this type most extensively characterized are those described by Hoy (1979) and Bassett and Hoy (1980) which were prepared by copolymerizing methyl methacrylate, butyl acrylate, and ethji acrylate with an unsaturated add such as itaconic, aciyh c, or methylacrylic. The particles obtained appeared to consist of a spherical core particle sur-... 

Poly(acrylates) and poly(methacrylates) form another class of common polymers with saturated carbon chain backbone. Polyacrylates can be considered vinyl polymers with the -COOR group attached at every other carbon atom in the chain. However, due to their common use and particular properties, polyacrylates form a separate polymer class together with polymethacrylates. Among the most common polymers from this class are those obtained from acrylic acid methyl ester (PMA) and methylacrylic (methacrylic) acid methyl ester (PMMA). Acrylic polymers have many practical applications in automotive industry, in the production of medical materials, paints, coatings and lacquers, adhesives, textiles, and synthetic leather. Poly(methacrylic acid methyl ester) can be obtained in cast sheets with applications in technical components, furniture, building materials, etc. Formulas for poly(acrylic acid), two polyacrylates, and poly(methyl methacrylate) are shown below ... 

Since the Arimoto/Haven report of vinylferrocene polymerization was not detailed, this monomer was made and both its homopolymerization and its copolymerization were studied with a variety of organic comonomers such as styrene, methylacrylate, maleic anhydride, acrylonitrile, methyl methacrylate, N-vinylpyrolidone, vinyl acetate, and so on.31-38 The polymers were as well characterized as possible, and copolymer compositions were obtained versus feed mole ratios.

METHYL METHACRYLATE or METHYL a-METHYLACRYLATE or METHYL METHACRYLATE MONOMER (80-62-6) Forms heat-sensitive explosive mixture with air (flash point 50°F/10°C). Unless inhibited, forms unstable peroxides. Violent reaction with strong oxidizers, benzoyl peroxide, or other polymerization initiators. Elevated temperatures, light, contamination can cause spontaneous, explosive polymerization. Incompatible with caustics, nitrates, strong acids, aliphatic amines, alkanolamines, peroxides. Flow or agitation of substance may generate electrostatic charges due to low conductivity. The uninhibited monomer vapor may block vents and confined spaces by forming a solid polymer material.

Different types of chemical initiators such as FAS-KPS, benzoyl peroxide, azo-bis-iso-butylnitrile, H O, ascorbic acid-KPS, ammonium persulphate, ceric ammonium persulphate, ceric ammonium nitrate, etc., can be used for the graft copolymerization of various vinyl monomers such as methylacrylate, methyl methacrylate, acrylic acid, methacrylic acid, ethyl methacrylate, vinyl acetate, acrylamide, etc., onto polysaccharides [38-40]. Figure 2.1 shows the proposed mechanism through which the grafting can be explained [39].

Even when PPS has superior chemical resistance and heat stability, its brittleness may be a drawback for certain applications. The physical properties of PPS can be improved by the addition of small amounts of terpolymers of ethylene, methylacrylate, and glycidyl methacrylate, also in a grafted variant with poly(methyl methacrylate) [59]. The manufacture of the composition occurs by melt mixing under a high shear rate.

Using the CTC equilibrium constants (table in the appendix to this chapter) it is possible to calculate the true reactivity values for the CTC and for the neutral monomer. Raetzsch and coworkers used this procedure for the cyclopentene-MA and norbornene-MA copolymerizations with acrylonitrile (Table 10.23). The same technique was also used to determine the reactivity constants for several other donor-acceptor-neutral monomer polymerizations (Table 10.23). For the NVP-MA-methyl methacrylate system the true reactivity ratios show the NVP-MA CTC is about 3 000 times the reactivity of NVP and 600 times the reactivity of methyl methacrylate toward the propagating radical ending in methyl methylacrylate.Results of this type support the concept of alternating copolymerization of a CTC with neutral monomer.
