A systematic comparative study of triblock terpolymers in the bulk and thin-film state was carried out on polystyrene-fo-poly(2-vinyl pyridine)-fc-poly(ferf-butyl methacrylate), PS-b-P2VP-fc-PfBMA. A diblock precursor with a minority of PS leading to a double gyroid structure was used. Upon increase of PtBMA content this morphology changed from lamellae with... 

Although it is generally difficult to find polymer pairs that mix homogeneously, PHOST partially protected with THP or tert-butoxycarbonylmethyl group has been reported to be miscible with a novolac resin or PHOST and to function as a dissolution inhibitor [124,132]. Another acid-labile polymeric dissolution inhibitor is a terpolymer of tert-butyl methacrylate (TBMA), methyl methacrylate (MMA), and methacrylic acid (MAA), which is miscible with a novolac resin [179] while PTBMA is not [159]. This methacrylic terpolymer is only marginally miscible with PHOST but more compatible with C- and... 

A terpolymer of ter/-butyl methacrylate (TBMA), methyl methacrylate (MMA), and methacrylic acid (MAA) was initially developed as a chemically amplified thick laser resist for circuit board fabrication [ 180]. The terpolymer containing 1 wt% of di(ferf-butylphenyl)iodonium trifluoromethanesulfonate (triflate) has demonstrated excellent imaging at 193 nm when developed with a dilute (0.01 N) TMAH aqueous solution [181]. This terpolymer single layer resist was employed for exposure tool testing.

The variability in the pyrolysis profiles of the different classes of coatings is self-evident. The interpretation of the composition revealed is as follows The acrylic lacquer (General Motors) is a methyl methacrylate/methacrylic acid copolymer plasticized with dibutyl-, butyl cyclohexyl-, and butyl benzyl phthalates. The acrylic enamel (Ford) is a styrene/ethylhexyl acrylale/methyl methacrylate terpolymer. The alkyd enamel (Honda) pyrolysis profile indicates that the paint resin is an orthoph-thaUc alkyd containing a butylated-amino resin cross-linking component.

With this knowledge also dual-stimuli-responsive micellar aggregates with a compartmentalized shell have been formed in aqueous solution from ABC triblock terpolymers with tunable hydrophilicity polybutadiene-fc/ocfc-poly (terf-butyl methacrylate)-fc/oc -poly(2-(dimethylamino)ethyl meth-acrylate) (PB-ii-PfBMA-fc-PDMAEMA) and, after modification by hydrolysis to poly(methacrylic acid) (PMAA) or quatemization to PDMAEMAq, PB-fc-PMAA- -PDMAEMAq terpolymers. Control over micellar shape, size, and charge was achieved by self-assembly in water, depending on pH and... 

The composition and microstracture of polymers in a latex system were studied by pyrolysis gas chromatography. The composition and microstructure of a polymer in the emulsion phase were identified by direct pyrolysis of the latex system, followed by comparing the trimer peak pattern with appropriate microstructure standards. The polymer in the aqueous phase was pre-pyrolysis derivatised with tetrabutylammonium hydroxide to convert the acid to its butyl ester. Similar procedures were then used to explore the composition and microstructure of the polymer in the aqueous phase. Polymers analysed included SCX-2660 (probably a styrene-methyl methacrylate-butyl acrylate terpolymer), styrene-butyl acrylate copolymer and styrene-alpha-methylstyrene-butyl acrylate terpolymer. 17 refs. 

The first miktoarm star terpolymers containing three different arms were presented by Fujimoto et al. [54]. They used a special technique to combine three different blocks (t-butyl methacrylate. 

PyGC is also an effective method for identifying and differentiating the organic binder of paint. In some cases, paint additives may readily be detected and identified. Automotive paint binder types can be identified on mg-sized samples of topcoat. Challinor [567] has evidenced various phthalates (DBP, BBP, BCP) in a methyl methacrylate (MMA)-butyl methacrylate (BMA) copolymer, BBP in a MMA-BMA-MA (methacrylic acid) terpolymer, DBP and BCP in MMA-MA copolymer and BBP in MMA-EA (ethylacrylate) copolymer. Paint additives may also be identified in architectural paints. Dimethyl orthophthalate (DMOP) was detected in an architectural alkyd enamel which had been subjected to simultaneous pyrolysis methylation (SPM) [635]. Industrial finishes on a beverage can also contain a variety of plasticisers (DMA, DMOP, DMIP), as also determined by SMP-GC [567]. 

Mao and co-workers [44] applied Py-GC to acrylic resins - including ethyl acrylate - butyl methacrylate copolymer and ethyl acrylate-styrene-ethylmethacrylate terpolymers.

The first ternary star copolymers containing three different arms were presented by Fujimoto and coworkers [81], They used a special technique to combine three different blocks (tert-butyl methacrylate, styrene, and dimethylsiloxane) which were all synthesized by living anionic polymerization. PDMS was synthesized by initiation with a functionalized 1,1,-diphenyl ethylene (DPF). In a second step living polystyrene anions were reacted with the DPF linked to the PDMS, before the tert-butyl methacrylate was added to give the 3-miktoarm star terpolymer. Several years later the morphological properties of these star copolymers were published as well. TFM and SAXS support a threefold symmetry where the junction points between the three incompatible blocks are confined on one line [221]. 

Most work in this area has been carried out for 3-miktoarm star terpolymers, which are stars composed of three chemically different arms. The first work on a system showing three different microdomains was performed by the group of Fujimoto on PS, PDMS, and poly(t-butyl methacrylate) (PtBMA). Hadjichristidis group first synthesized 3-miktoarm star terpolymers of PS, PB, and PI. This system showed a two-microphase stmrture, as the two mbbery blocks do not segregate from each... 

Py-GC has also been applied to structural studies on uncured polyesters containing acrylate [18], ethyl acrylate - methylmethacrylate copolymers [57] and 2-hydroxy methacrylate - butyl acrylate - ethyl methacrylate terpolymers [58]. 

Numerous recipes have been pubUshed, primarily ia the patent Hterature, that describe the preparation of acrylate and methacrylate homopolymer and copolymer dispersions (107,108). A typical process for the preparation of a 50% methyl methacrylate, 49% butyl acrylate, and 1% methacrylic acid terpolymer as an approximately 45% dispersion ia water begias with the foUowiag charges ...
