Butyl acrylate acrylic acid

In nonrigid ionomers, such as elastomers in which the Tg is situated below ambient temperature, even greater changes can be produced in tensile properties by increase of ion content. As one example, it has been found that in K-salts of a block copolymer, based on butyl acrylate and sulfonated polystyrene, both the tensile strength and the toughness show a dramatic increase as the ion content is raised to about 6 mol% [10]. Also, in Zn-salts of a butyl acrylate/acrylic acid polymer, the tensile strength as a function of the acrylic acid content was observed to rise from a low value of about 3 MPa for the acid copolymer to a maximum value of about 15 MPa for the ionomer having acrylic acid content of 5 wt% [II]. Other examples of the influence of ion content on mechanical properties of ionomers are cited in a recent review article [7],... 

Studies of the particle—epoxy interface and particle composition have been helpful in understanding the rubber-particle formation in epoxy resins (306). Based on extensive dynamic mechanical studies of epoxy resin cure, a mechanism was proposed for the development of a heterophase morphology in rubber-modified epoxy resins (307). Other functionalized mbbers, such as amine-terminated butadiene—acrylonitrile copolymers (308) and tf-butyl acrylate—acrylic acid copolymers (309), have been used for toughening epoxy resins. 

The modulus in this case is the secant modulus at 1% strain. Both polymers had the same composition 39/59/2 - methyl methacrylate/ butyl acrylate/acrylic acid. The power feed example was prepared such that butyl acrylate varied 0.83 — 0.30 and methyl methacrylate varied 0.15 — 0.68 as the polymerization proceeded, with x = 0.83. While both examples show the usual trend of high modulus at low temperature to low modulus at higher temperature, the power feed polymer exhibits a much broader transition region than the uniform example. 

Recently Uniqema has introduced commercially a Surfmer under the trade name of Maxemul 5011. Maxemul is produced by esterification of an unsaturated fatty anhydride with a methoxy PEG such that the reactive group is close to the hydrophilic moiety [ 34 ]. Stable latexes with a solid content of 52% were produced in the seeded emulsion polymerization of film-forming methyl methacrylate/butyl acrylate/acrylic acid (3% Surfmer on monomers, constant monomer feeding rate over 4 h, potassium persulfate/sodium metabisulfate redox initiator). The latexes were stable to electrolytes but not to freeze-thaw.

An unusual process features a spun polythene band ich has been impregnated with blended acrylic latices, e.g, containing 1,4-butanediol diacrylate, ethyl acrylate and acrylic acid in 1 component, and l,4 butanediol diacrylate, butyl acrylate, acrylic acid and NllAM in a second. 1 of the photosensitiser, benzoin isopropyl ether is also present. The impregnated band is drawn across an irradiation zone vdiilst resting on a thin layer of ice, thence forming a continuous leather - like band. (20)...

Preferred monomers are alkyl (meth)acrylates, such as butyl acrylate, acrylic acid, and y-methacryloxypropyl triethoxysilane. A reactive emulsifier is used which refers to an emulsifier that has an emulsifying capability and is radically polymerizable. 

Acrylic resins are used in latex paints. The latex binders are copolymers of two to five monomers, e.g., butyl acrylate, acrylic acid and styrene. Lattices are made by emulsion polymerization of the monomers dispersed in water as droplets. Polymerization takes place in these droplets and is initiated by, for example, benzoyl peroxide. The lattices may contain small amounts of ammonia (0.3% w/w), formaldehyde (0.06% w/w) or other biocides (e.g., a mixture of isothiazolinones), surfactants and polymerization inhibitors (e.g., p-methoxy phenol or hydroquinone). (Mathias 1984 Hansen et al. 1987 Fischer and Adams 1990). 

The following unsaturated epoxy compounds have been used to prepare via free-radical initiation several different epoxy resins by reaction with methyl methacrylate, butyl acrylate, acrylic acid, styrene (or mixtures of the latter monomers) [86]. 

The chemistry of real latex formations is complex and currently defies predictive modeling. A reported problem for waterborne modelers is that an increase in curing temperature can affect various coating components differently. Snuparek and colleagues added a nonionic emulsifier to a dispersion of copolymer butyl meth-acrylate/butyl acrylate/acrylic acid. When cure took place at room temperature, the water resistance of the films increased with the amount of emulsifier added. When cure happened at 60°C, however, the water resistance of the films decreased with the amount of emulsifier added [4]. 

Lee and coworkers [207] obtained similar results by using a family of n-butyl acrylate/acrylic acid (nBA/AA) copolymers with a broad functionality range (1.62-9.93). They reported, in fact, that improvements in adhesion strength could...
