Zonyl® methacrylate

Fig. 3.2.9 DSC/TGA of the RBl-200 product, which contains segments from VDC, Zonyl methacrylate, methyl methacrylate (MMA), and glycidyl methacrylate(GMA). The run includes a heat-up step to 200°C, then a cool-down step to room temperature, followed by a final heatup step. Both heat-up and cool-down steps are at 10°C/min rate. Note that exotherm is up in the vertical axis...

The copolymers were synthesized by radical initiated copolymerization of methacrylate monomers in butanone under inert conditions (dry nitrogen atmosphere). As initiator 2,2 -azobis-(2-methyl propionitrile) (AIBN) was employed. The copolymers obtained were used without further purification. The following example to produce the copolymer poly [methyl methacrylate-co-Zonyl TM-co-2-(methacryloyloxy)ethyl acetoacetate] (Table 1, polymer 21b) from three monomers illustrates the typical synthesis ...

Figure 3. XPS wide-scan spectra of a poly[ferf-butyl methacrylate-co-Zonyl TM-co-2-(methacryloyloxy )ethyl acetoacetate], 8 1 1 film (polymer 11b) removed from a glass substrate. Spectrum (a) was recorded from the copolymer side which was directed towards the air, while spectrum (b) refers to the copolymer side which was in contact with the glass substrate. The atomic concentrations are given in Table 4.

An example product is a diblock called RBI-232 made of a VDC copolymer (96 wt% VDC, 6 wt% Zonyl TA-N) block with a butyl acrylate-Vaf-glycidyl methacrylate block. The reactor product solution was fractionally precipitated, and... 

Radicalized VDC statistical copolymer with Zonyl has been shown to be capable of formation of various block copolymers, which in turn can also be reactive intermediates. This is true with the RBl-200 and RBI-232 products described in Section 4.2, in which the second block contains epoxide groups from glycidyl methacrylate. Another product, called RBI-201, was similar to RBl-200 but contained Zonyl TM segments in the second block (see synthesis procedure in Table 4.3.1).
