Typical acrylic resins are high MW polymers or copolymers of acrylate and/or methacrylate monomers prepared by radical-initiated chain-growth polymerization (see Figure 2.28). In addition to the (meth) acrylate monomers, other functional (meth)acrylate monomers as well as non-acrylate monomers (typically vinyl monomers) are frequently used in preparation of commercial acrylic copolymer resins to impart reactive functionality or special properties or for lower cost. Some examples of these monomers are shown in Figure 2.29. 

In the foUowiag cases, only those reactions ia which there is no chain growth, or at most dimerisation, are considered (see Olefin polymers). Alkyl titanium haUdes can be prepared from alkyl aluminum derivatives. The ring stmcture imparts regiospecificity to the ensuing carbometalation (216) ...

The reaction of AgOTf with a flexible diimine ligand in 1 2 and 1 1 ratio leads to the mono- or dinuclear complex, respectively. They further react with AgOTf to give coordination polymers. These complexes are models for the chain-growth process required in the formation of coordination polymers (see Scheme 2).642,643 Similar complexes are obtained with the 1,4-di-t-butyldia-zabut- 1,3-diene derivative.644... 

It is difficult to see how the presence of two double bonds in each polymer molecule (reported by Eley and Richards for the polymerisation of 2-ethyl hexyl vinyl ether) can be explained without assuming that the chain is started by an unsaturated entity, and that the second double bond is formed in the termination process. Since the chain growth is almost certainly a carbonium ion process the initiating entity must be a positive ion of some sort. We assume therefore that the ether is split into two ions under the influence of the catalyst. This may obviously occur in two different ways, but energetic considerations can show which of these will in fact take place. 

The polymer literature yields a variety of specialized move types in particular for lattice homopolymers [110]. Sampling methods like the slithering snake and reptation algorithms (see ref. Ill and references therein) or the original configurational-bias/chain growth algorithms [112,113] were specifically... 

The block mechanism of chain assembly is characteristic for polymeric chains of the UGT type (see Salmonella O-specific polysaccharides 10-12 and 18) and the UG type (see capsular polysaccharides 25, 27, and 33), with UDP-activated sugars serving as initiators of chain growth. It seems rather safe to suggest that the biosynthesis of other polymers of these types occurs through a block mechanism as well.
