在第8章中解释了MA不容易均聚。然而，已知该单体将容易地与多种其它单体共聚。事实上，许多1，2-取代的单体，由于动力学效应通常不会进行自由基聚合，将产生与MA存在的共聚物。这是真的，MA共聚继续进行研究，为更好地理解这些共聚为什么和如何发生的机理。此外，MA共聚作为一种通过提供增加的极性、刚性、玻璃化转变温度和功能性来改善聚合物的物理化学性质的技术正在被探索。已知聚合物主链上的MA残基促进亲水性和粘附性，改善可染性和热变形，赋予交联和其它化学改性的官能度，以及促进与其它聚合物和填料的相容性。我们将在本章和第10章中看到，这些物理和化学属性是如何被利用来制造许多共聚物的，这些共聚物在涂料、粘合剂、塑料和纤维工业中是有用的或潜在有用的。
It was explained in Chapter 8 that MA is not easily homopolymerized. However, it is known that this monomer will readily copolymerize with a great variety of other monomers. In fact, many 1,2-substituted monomers, which will not normally undergo free-radical polymerization due to kinetic effects, will yield copolymers with MA present. This being true, MA copolymerizations continue to be studied, for a better mechanistic understanding of why and how these copolymerizations occur. Also, MA copolymerizations are being explored as a technique to improve the physicochemical properties of polymers by providing increased polarity, rigidity, glass transition temperature, and functionality. The MA residue on the polymer backbone is known to promote hydrophilicity and adhesion, improve dyeability and heat distortion, give functionality for crosslinking and other chemical modifications, as well as promote compatibility with other polymers and fillers. It will be seen in both this chapter and Chapter 10, how these physical and chemical attributes have been exploited to make many copolymers, useful or potentially useful in the coatings, adhesives, plastics, and fiber industries.
