Methyl methacrylate-ethylene glycol

The first case is the copolymerization of monomer A with diene BB where all the double bonds (i.e., the A double bond and both B double bonds) have the same reactivity. Methyl methacrylate-ethylene glycol dimethacrylate (EGDM), vinyl acetate-divinyl adipate (DVA), and styrene-p- or m-divinylbenzene (DVB) are examples of this type of copolymerization system [Landin and Macosko, 1988 Li et al., 1989 Storey, 1965 Ulbrich et al., 1977]. Since r = Yi, Fi = f and the extent of reaction p of A double bonds equals that of B double bonds. There are p[A] reacted A double bonds, p[B] reacted B double bonds, and p2[BB] reacted BB monomer units. [A] and [B] are the concentrations of A and B double bonds,... 

Optically active phosphine monoester 69 was prepared as a stable transition state analogue of the hydrolysis of 70, and used as a template (Scheme 13.17) [52], When heated in the presence of amidine 72, methyl methacrylate, ethylene glycol dimethacrylate and AIBN, polymerization took place and offered the polymer 73, in which the template 69 is attached to the binding sites by a combination of hydrogen bonds and electrostatic interactions. After washing in the presence of MeOH and aqueous NaOH, the template was removed from the cavity, thus leading to a catalytically active MIP. 

Any relatively involatile monomer with the vinyl (CH2 = CH-) or vinylidene (CH2 = C<) grouping present is theoretically suitable. In practice, many are not sufficiently reactive. Of the remainder, styrene is very reactive and cheap. It is usually the chief (or only) monomer, but may have a comonomer such as vinyl toluene, methyl methacrylate, ethylene glycol dimethacrylate, triallyl cyanurate or diallyl phthalate. 

Similar data are available with styrene/divinylbenzene and methyl-methacrylate/ethylene glycol dimethacrylate copolymers (the second molecule providing cross-links). 

An internal-reflection prism cell has been used for reaction-kinetics measurement of styrene-unsaturated polyester resins at elevated curing temperatures and pressures [133]. Other researchers have estimated the cross-linking efficiency in methyl methacrylate-ethylene glycol dimethacrylate copolymer networks by laser Raman spectroscopy [134], while recently... 

SBA is primarily used as feedstock for methyl ethyl ketone. Other uses include hydraulic fluids, industrial cleaning compounds, paint remover, and an extracting agent for oils, perfumes, and dyes. TBA is used mostly as feedstock to make methyl methacrylate and glycol ethers (by reaction with ethylene or propylene oxides.) TBA is also a coproduct with PO, as covered in Chapter 11.

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. 

One of the calculation results for the bulk copolyroerization of methyl methacrylate and ethylene glycol dimethacrylate at 70 C is shown in Figure 4. Parameters used for these calculations are shown in Table 1. An empirical correlation of kinetic parameters which accounts for diffusion controlled reactions was estimated from the time-conversion curve which is shown in Figure 5. This kind of correlation is necessary even when one uses statistical methods after Flory and others in order to evaluate the primary chain length drift. 

II. B polyethylene glycol, ethylene oxide, polystyrene, diisocyanates (urethanes), polyvinylchloride, chloroprene, THF, diglycolide, dilac-tide, <5-valerolactone, substituted e-caprolactones, 4-vinyl anisole, styrene, methyl methacrylate, and vinyl acetate. In addition to these species, many copolymers have been prepared from oligomers of PCL. In particular, a variety of polyester-urethanes have been synthesized from hydroxy-terminated PCL, some of which have achieved commercial status (9). Graft copolymers with acrylic acid, acrylonitrile, and styrene have been prepared using PCL as the backbone polymer (60). 

Most of the polymers are better known by their trivial names or trade names. Polymers prepared from single polymers are denoted by prefixing poly- to the name of the monomer, e.g., polyethylene, polypropylene, Polyacrylonitrile, polystyrene, etc. If the monomer has substituents or has a multi-worded name, the name of the monomer is enclosed in parenthesis after the prefix poly-, e.g., poly (methyl methacrylate), poly (vinyl alcohol), etc. Condensation polymers like that derived from ethylene glycol and terephthalic acid are named as poly (ethylene terephthalate). 

The major one-carbon feedstock is methane and it serves as the feedstock to a number of important monomers including hexamethylene tetramine and melamine, used in the synthesis of a number of cross-linked thermosets as well as vinyl acetate, ethylene, ethylene glycol, and methyl methacrylate (Table 17.1).
