Styrene butyl acrylate

Since this pioneering work a number of IPNs have been prepared. Poly(styrene) has been used as the second network polymer in conjunction with several other polymers, including poly(ethyl acrylate), poly(n-butyl acrylate), styrene-butadiene, and castor oil. Polyurethanes have been used to form IPNs with poly(methyl methacrylate), other acrylic polymers, and with epoxy resins. 

This study was therefore undertaken to prepare and evaluate acrylonitrile—butadiene-styrene (ABS) and methyl methacrylate-butadiene-styrene (MBS) polymers under similar conditions to determine whether replacement of acrylonitrile by methyl methacrylate could improve color stability during ultraviolet light aging, without detracting seriously from the good mechanical and thermal-mechanical properties of conventional ABS plastics. For purposes of control, the study also included briefer evaluation of commercial ABS, MBS, and acrylonitrile-butyl acrylate-styrene plastics.

Some rather interesting, if complex, materials have been prepared by Vollmert (18). Previously we considered some of his materials composed of two polymers now we will consider mixtures of three or more polymers. (Notations relating to mode of polymerization and state of the polymer (14, 15) are omitted for clarity.) Because the individual polymers, in most cases, are multi-mer random copolymers in their own right, one monomer will be considered per polymer for simplicity in the following. In his example 5, the Vollmert emulsion polymerized 7i-butyl acrylate, styrene, 1,4-butanediol monoacrylate, and 1,4-butanediol... 

Material. Optically clear films (about 5 mils thick) of three SA (saturated acrylic) plastics (3) that contained 25, 33, and 50% of an acrylic graft rubber (referred to as SA-1, SA-2, and SA-3) were compression molded. The acrylic graft rubber latices were latex blended with a resin latex composed primarily of methyl methacrylate, and the blend was coagulated. The compositions of these three polymers are as follows SA-1, 79/17/4 wt %—methyl methacrylate/butyl acrylate/styrene SA-2, 72/23/5 wt %—methyl methacrylate/butyl acrylate/styrene SA-3, 59/34/7 wt %—methyl methacrylate/butyl acrylate/styrene. All three graft rubbers contained low levels of a crosslinking comonomer (less than 1.0 wt %). 

The Ziegler-Natta catalyst trimethylammonium o-methyl-1-(2-hydroxy Icy do hexyl)-carborane zirconium chloride has been prepared and affixed to a Merrifield resin. When used as a polymerization catalyst for vinyl chloride, t-butyl acrylate, styrene, or ethylene, oligomers with molecular weights <6000 daltons were obtained. 

The current work was concerned with the emulsion copolymerization of vinyl ferrocene with butyl acrylate, styrene, and methacrylic acid to yield a film-forming composition of Tg 0-5 C. 

In contrast to the claims of the literature, vinyl ferrocene (available commercially) was found to be a very reactive monomer in the terpolymer system butyl acrylate/styrene/methacryllc acid. It was further found, again in contrast to the claims in the literature, that vinyl ferrocene could be emulsion polymerized via organic peroxide Redox catalysis. 

The paint studied is a typical automotive thermosetting enamel which consists of an epoxy functional acrylic copolymer and butylated melamine crosslinking agent. The acrylic copolymer is composed of methyl methacrylate, n-butyl methacrylate, n-butyl acrylate, styrene, acrylonitrile, 2-ethyl hexyl acrylate and 2-hydroxyethyl methacrylate. Carbon black was used as the pigment.

The inisurfs can be used in emulsion polymerization without addition of surfactants to obtain, for example, butyl acrylate-styrene-copolymer dispersions with a solid content of about 35%.

Block copolymers of butyl acrylate-styrene and acrylonitrile-styrene have been prepared by irradiating butyl acrylate or acrylonitrile containing a photosensitive initiator (e.g., 1-azo-bis.l-cyanocyclo-hexane) with an intensive UV radiation. This creates a radical-rich monomer that when mixed with styrene yields the appropriate block copolymer.

Poly(vinyl ester) dispersions are quantitatively more important than solid resins. Homopolymer and copolymer dispersions are used for binders in emulsion (dispersion) paints, plastic-bonded plasters, and water-thinnable adhesives. Poly(vinyl acetate) dispersions are less important than vinyl acetate copolymer dispersions. The most important comonomers of vinyl acetate are vinyl laurate, dibutyl maleate, Versatic Acid esters (VeoVa, Shell), ethylene, vinyl chloride, and butyl acrylate. Poly(vinyl propionate) and copolymers of vinyl propionate with butyl acrylate, styrene, or vinyl chloride are also marketed and used as dispersions.

Some rather interesting, if complex, materials have been prepared by Vollmert (1962). For instance, in his example 5, Vollmert emulsion polymerized w-butyl acrylate, styrene, 1,4-butane-diol monoacrylate, and 1,4-butane-diol diacrylate, forming polymer I. Separately, n-butyl acrylate, styrene, and acrylic acid were emulsion-polymerized, forming polymer II. Polymers I and II were mixed, precipitated, washed, dried, and dissolved in styrene and acrylic acid, followed by polymerization, forming polymer III. The material was then heated to induce grafting between polymers I and II, and I and III.
