Self-cross-linking acrylates

Self cross-linking acrylic emulsion. Excellent product for compounded coatings. 

Self cross-linking acrylic copolymer. Excellent durability. Very tough polymer. 

Self cross-linking acrylic. Very soft hand, resistance. 

Like other acrylic copolymers, these self-cross-linking acrylic nitrogen resins may be produced as latices or in water-soluble form and formulated into water-based paints. 

Self cross-linking all-acrylic emulsion. Film has good elongation and tensile properties and does not discolor. Gives a soft, durable hand to fabrics. Reduces abrasion, improves wrinkle-resistance and crockfastness and aids in controlling shrinkage. T(g)-25C. 

Self cross-linking vinyl acrylic copolymer. Firm hand. 

The thermoset acrylics (20) of major importance in the coating industry, in recent years, have been developed primarily by Canadian Industry Ltd. and by Pittsburgh Plate Glass Co. in this country (4). Raw materials are acrylamide, acrylic acid, acrylates, and styrene. Cross-linking agents are amino and epoxy resins. The materials are also self-cross-linking. They are usually sold as solutions in paint solvents. 

The binder, therefore, must have the following properties good adhesion to fibre and pigment in the dry state, and in water and solvent a soft, non-tacky handle elasticity lightfastness, clarity and no colour compatibility with, and stability towards, other ingredients in the mix. Some styrene butadiene copolymer rubbers and vinyl latices are used successfully but the most suited are the acrylics. The polymers are usually either self-cross-linking (with heat) or incorporate a cross-linkable resin such as melamine-formaldehyde. 

The variability in the pyrolysis profiles of the different classes of coatings is self-evident. The interpretation of the composition revealed is as follows The acrylic lacquer (General Motors) is a methyl methacrylate/methacrylic acid copolymer plasticized with dibutyl-, butyl cyclohexyl-, and butyl benzyl phthalates. The acrylic enamel (Ford) is a styrene/ethylhexyl acrylale/methyl methacrylate terpolymer. The alkyd enamel (Honda) pyrolysis profile indicates that the paint resin is an orthoph-thaUc alkyd containing a butylated-amino resin cross-linking component. 

Another template-free method for the formation of self-assembled tubular structures has been shown by Jiang and co-workers. They used polymeric Janus particles prepared from mixed-shell micelles (MSMs) that self-assembled into tubular superstructures and nanosheets. The micelles were prepared by non-covalent cross-linking of poly(acrylic acid) (PAA) blocks by addition of 1,2-propanediamine (PDA) in DMF (A on Figure 5.45). The two block copolymers were composed of hydrophilic poly(ethylene...
