Chain reactions carried out on one type of monomer give rise to homopolymers when using two types of monomer the situation is more complicated. For example, polymerising mixtures of vinyl chloride with acrylate esters gives rise to a range of molecules, the first of which are relatively rich in acrylate molecules formed later, when the amount of acrylate monomer is relatively depleted, are richer in vinyl chloride. In a number of instances, reactions of this kind can be used to prepare polymers containing monomers which will not homopolymerise, e.g. maleic anhydride and stil-bene (vinylbenzene). [Pg.37]

Recently, polymerization of sodium acrylate on polyallylamine hydrochloride template was described. In aqueous solution, sodium acrylate molecules are adsorbed onto a template with ammonium cationic pendant groups. The complex was polymerized in water solution using AIBN or K2S2O8 as initiators. Polymerization proceeds according to reaction ... [Pg.35]

An example of such a simulation starting from the acrylate ir-complex is summarized in Figure 4-27, in which the crucial interatomic distances and selected geometries are displayed. The data in the figure show that at the end of the simulation the CT-complex is not formed. Instead, the methyl acrylate molecule dissociate. Similar results were obtained for the system with Pd-catalyst. Thus, MD simulations suggest a dissociative pathway for the interconversion reactions between the two binding modes. [Pg.259]

C—C coupling than the cation mechanism, but separation of the newly generated car-boxy group from zirconium proved to be exothermic and did not require assistance by an acrylate molecule. [Pg.72]

Figure 3 shows the simple case of a clock reaction competing with hydrogen atom transfer from tin hydride. If one wished to determine, for example, the rate of addition of a primary alkyl radical to an activated alkene such as an acrylate, then the reaction could be run at low concentrations of tin hydride such that both the radical clock and its rearrangement product reacted predominantly with the alkene. The products of the acrylate addition reaction are deactivated with respect to addition to another acrylate molecule, and one could control concentrations such that these adducts reacted primarily with the tin hydride (Scheme 3). In this case, then, one would analyze for the acrylate addition products of the unrearranged and rearranged radicals.

ENR/EVA blends. Irradiation produced the initiating free radicals that then reacted with a bismaleimide or a multifunctional acrylate molecule through unsaturation to produce cross-linking. The mechanism is given in Figure 9.7. The effective cross-linking by HVA-2 or TMPTA was confirmed by dynamic mechanical analyzer (DMA). [Pg.279]

Epoxy di(meth)acrylates (also caUed vinyl esters) are another name for the p-hydroxyester acrylates, because they are usuaUy obtained by reacting epoxy resins of glycidyl derivatives with (meth)acrylic acid. They can also be manufactured from bisphenol A and glycidyl (meth)acrylates. Although prepared from compounds containing reactive epoxy groups, completed epoxy di(meth)acrylate molecules do not contain these groups. Both aromatic and aliphatic epoxy di(meth)acrylates are available, as weU as acrylated epoxydised oUs (Jolanki 1991 Jolanki et al. 1995). [Pg.572]

To some extent, the stability of VDC polymers is dependent on the nature of the comonomer present. Copolymers with acrylates degrade slowly [41, 42]. Apparent degradation propagation rates decrease somewhat as the acrylate content of the copolymer increases [41]. The polyene sequences generated by dehydrochlorination are limited in size by the level of acrylate incorporation that is, the acrylate molecules act as stopper units for the unzipping reaction. The impact of this chain stopping is that the... [Pg.213]

The same results have been obtained during the simulation of the n methyl acrylate molecule aggregation. This data confirms the aggregative nature of oligomeric systems and it is used in [173] for the explanation of the drying kinetics anomalies of unsaturated oligomers. [Pg.111]
