Methylacrylate ethene

Results of similar quality can also be obtained for copolymers in which the segments are not as similar as in the previous example. Figure 13 shows the solubility of ethylene-co-alkylacrylate copolymers in ethane [42]. For the poly (ethylene-co-propylacrylate) copolymer, the solubility increases with an increasing amount of propylacrylate monomers in the copolymer backbone (Fig. 13b). In contrast, the poly(ethylene-co-methylacrylate) solubility first increases (cloud-point pressure decreases) due to favorable methylacrylate-ethene interactions but,... 

The reaction of (dppe)PtMe(OMe) (dppe = bis(l,2-diphenylphosphino)ethane) with F2C=CF2 has been shown to give (dppe)PtMe(CF2CF20Me), providing the first example of an alkene insertion into an M-OR bond. Interestingly, the platinum alkyl-alkoxide complex does not react with ethene or pentene but similar to 4-tetrafluoro-ethylene other activated alkenes such as acrylonitrile and methylacrylate also undergo insertion reactions. It is noteworthy that the reaction does not involve nucleophilic attack on a coordinated alkene by free methoxide ion. The transformation of a M-OR bond into a M-R bond appears to be thermodynamically favourable in this instance. 

Alternating copolymers of 1,3-butadiene with ethene, propene, acrylonitrile, isobutene, and 2-methylacrylic acid methyl ester are known [503-513]. Suitable catalysts are titanium and vanadium compounds. The stereoregularity of the butadiene units is...
