Acrilic Copolymer

The most important compolymers are those acrylonitrile. The acrylonitrile butadiene copolymer has its widest use in the form of the latex, and is used for sticking a variety of absorbent materials, including ceramic will tiles. another use is in making bonded (non-woven) fabrics; here softness, resistance to laundering and dry cleaning, and excellent adhesion to textile fibres including cotton, rayon nylon and polyester are essential properties.

In general, variation of the monomer ratio has a marked effect on the polarity of the copolymer, particularly if one monomer is highly polar such as acrylonitrile, and the other highly non-polar such as butadiene. With polymer derived from monomers of widely different adherends will be influenced by the monomer ratio.

Acrylonitrile Adhesive

Acrylonitrile adhesive is a highly reactive and an extremely important monomer in the field of plastic and rubbers. The most important use of acrylonitrile is in forming copolymers. As a chemical intermediate, however, it is used for producing acrylic acids, as mention earlier and also another useful acrylic polymer, polyacrylamide.

Acrylamide:
Acrylamide (and methacrylamide) are prepared from the appropriate nitriles. They polymerise to produce film substances with adhesive uses. Polyacrylamide, although water soluble, is not inconveniently hygroscopic. It is important and useful as a thickener and as dispersing agent in adhesive compositions, and also as an adhesive by itself for paper and other cellulose materials.
