Poly methacry lates

Recommended initiators for methacrylate polymerizations are 1-24 (X = Br) and 1-25 (X = Cl), both of which are unimer and dimer models of poly(methacry-late) dormant terminals, respectively. For example, PMMA with precisely controlled molecular weights, very narrow MWDs (MJMn — 1.1), and nearly perfect end-capping with halogen was obtained with the 1-25 (X = Cl)/Ru-5/Al(0-7-Pr)3 initiating system.60 197 Alternatively, arenesulfonyl chlorides can lead to well-controlled poly (methacrylate) s with narrow MWDs (MJMn = 1.1 —1.2) in combination with copper catalysts.126176... 

Thus the quantity on the left evaluated for a series of polymer fractions differing only in chain length should be independent of M. Results shown in Table XLII for fractions of poly-(methyl methacry-late) and of polyisobutylene covering unusually wide ranges confirm this prediction within experimental error. It is borne out also by less extensive results of sedimentation measurements on several other systems. Introduction of the values of v, p, and rjo enables...

As an example of blends with attractive interactions, Fig. 65 shows a superstructure in which interactions between methacrylic acid groups and pyridine side groups of a polystyrene-fc-polybutadiene-fo-poly(f-butyl methacry-late-staf-methacrylic acid) (PS-b-PB-b-P(MAA-sfaf-fBMA)) triblock quater-polymer and a PS- -P2VP diblock copolymer lead to a wavy lamellar structure with cylinders from mixed P2VP and P(MAA-sfaf-fBMA) blocks [194],...

It is noteworthy that the polymerization of MAOA, particularly in the presence of isotactic polyMAOU, is eminently accelerated at 20 °C but not at 40 C in pyridine solution. Such an acceleration at low temperature was also observed for the polymerization of methyl methacrylate in the presence of isotactic poly(methyl methacry-late) In our case, it can be suggested that isotactic polyMAOU has a special conformation at 20 C which is favored by the formation of a complex between this polymer and a growing chain of MAOA. This conformation may be a helix, as reported for isotactic poly(methyl methacrylate) and may change into a random coil at higher terqjerature.

If a mesogenic monomer is copolymerized with a nonmesogenic monomer, the mesophase is observed above a minimum concentration of the mesogenic monomer. For example, neither poly (methyl meth-acrylate)-co-[6-[4 -(4"-cyanophenylazo)-phenoxy]hexyl methacrylate]) DP 35, pdi =1.35) nor poly (methyl methacry late)-co-[6-[4 -(4"-n-butoxyphenoxycarbonyl)-phenoxy]hexyl methacrylate] DP 69, pdi =1.12) (Scheme 36) prepared by metal-loporphyrin-initiated copolymerizations and containing 18-20 mol% of the mesogenic monomer exhibit the SmA mesophase of the corresponding SCLCPs [90].

The prefix g describes graft copolymers and the prefix b describes block copolymers. In this system of nomenclature, the first polymer segment corresponds to the homopolymer or copolymer that was formed during the first stage of the synthesis. Should this be a graft copolymer then this will represent the backbone polymer. For instance, if polystyrene is graft copolymerized with polyethylene, the product is called poly(ethylene-g-styrene). A more complex example can be poly (butadiene-co-styrene-g-acrylonitrile-co-vinylidine chloride). Similarly, examples of block copolymers would be poly(acrylonitrile- -methyl methacrylate) or poly(methyl methacry late- -acry lonitrile).

Macromolecules having a flexible side chain carrying a dipole moment are called to be of type C (Block 1979). A typical example are poly(n-alkyl methacry-late)s. This definition is only appropriate tmder the condition that the side chain can fluctuate on a shorter time scale than the segmental dynamics of the macromolecule. Otherwise the polymer is of type B.

In our previous paper we reported that two kinds of active species exist in the anionic polymerizations of ethyl methacry-late(EMA)(5).
