Vinylidene chloride is readily polymerized but the homopolymer does not have sufficient thermal stability to withstand melt processing. The homo-polymer is not therefore of commercial importance. However, by the copolymerization of vinylidene chloride with lesser amounts (generally 10-30%) of a vinyl monomer, processable copolymers may be obtained. The comonomers most widely used for this purpose are vinyl chloride and acrylonitrile. 

The binding of pyridoxal 5 -phosphate (vitamin Be) to enzymes has been modelled using homo- and co-polypeptides containing L-lysine as a source of reactive amino groups. This has now been extended to reaction of pyridoxal with polyallylamine, with the polymer acting as a control that cannot provide amido -CO- or -NH- functions to stabilize the Schiff base products, as occurs in enzymes and polypeptides. Rate constants for the formation and hydrolysis of the imines have been measured and interpreted in terms of formation of the carbinolamine (in its neutral or zwitterionic form). 

Interest in cyclic olefin (co)polymers has increased dramatically over the past decade. This is because this class of polymers displays many attractive properties such as high thermal stability, high optical transparency, low dielectric constants, and low moisture absorption. Thus, these polymers can potentially be utilized in many electronic and optical applications. Although cyclic olefin (co)polymers typically include ring-opening metathesis polymers, vinyl-addition homopolymers, and vinyl-addition co-polymers with acyclic co-monomers such as ethylene, we will mainly deal with vinyl-addition homo- and co-polymers in this section.

P-atom due to an inductive effect, hence destabilizing the HOMO. The LUMO of the chromophore Pd(CNR)2(P) is stabilized, going from a saturated chain P(CI I2) P to P—C=C—P, via coupling of the empty d orbitals located onto P and the empty ir-orbital located onto ethynyl fragment. The emission lifetimes in these polymers were surprisingly short (a few ns). Nevertheless, the quantum yields obtained are larger than expected for such short lifetimes (Table 5). This phenomenon remains unexplained.
