In Table 7.33 is shown some results obtained by applying this method to a range of acrylic polymers. The calculated recoveries are greater than 95%, for polymers containing between 10% and 100% acrylic monomer. The method has 99% confidence interval of 0.8. The presence of comonomers such as styrene, acrylonitrile, vinyl acetate, acrylamide or acrylic acid does not change the recovery of acrylate or methacrylate esters. Non-quantitative results are obtained, however, for polymers containing hydroxy-propyl methacrylate. 

Dispersions of copolymers of butadiene with acrylic acid or methacrylic acid in aqueous potassium hydroxide have been mentioned in the patent literature" as a dip for adhering rayon tire cord to rubber. The effect is most evident when carboxyl groups are present in the adhesive, the tie cement, and the cover stocks. The adhesive may be applied as latex, aqueous dispersion, or cement. A patent issued to the Dunlop Company Ltd." describes the use of a styrene-butadiene-itaconic acid copolymer with Gen-Tac Latex (GenCorp) in formulating an RFL (resorcinol formaldehyde latex) type adhesive for bonding a natural rubber compound to Nylon 66 and rayon tire cords. Brodnyan" also claims carboxylic adhesives for rayon, nylon, and Dacron cords. In this case, the tire cords were treated with a mixed polymer latex containing resorcinol-formaldehyde condensate, a butadiene-vinyl pyridine copolymer, an SBR copolymer, and a multifunctional copolymer from methyl acrylate, 2-hydroxy propyl methacrylate, and acrylic acid. A different approach was reported by Badenkov" whereby rayon or nylon tire cords were coated with...

Frequently, hydroxyl functional monomers are used as part of the copolymer with the hydroxy group providing the site for crosslinking with, for example, an amino crosslinker, when the coating is stoved. Two hydroxy functional types have been shown. Hydroxyl ethyl has a terminal (primary) hydroxyl group which is more reactive than the secondary hydroxy group on the hydroxy propyl chain. It is thus possible to get more rapid cure response by incorporation of hydroxy ethyl rather than hydroxy propyl functionality in the acrylic copolymer. This, however, may not always be advantageous as frequently rapid cure can lead to poor adhesion. 

The data shown in Scheme 12.7 confirm that addition of (substituted) benzoyl radicals is slower than that of counter radicals (Scheme 12.7b), and therefore the benzoyl adducts have weak signals in the TR ESR spectra. A similar conclusion was obtained by FT TR ESR study of the photolysis of IRG2959 in the presence of NBA (Schemes 12.1 and 12.3)." ° ESR signals of two products of photolysis of IRG2959, namely, 2-hydroxy-2-propyl radical and substimted benzoyl radical, demonstrate quite different time dependences in the presence of acrylate. The signal of 2-hydroxy-2-propyl radical disappears faster with an increase in acrylate concentration, whereas benzoyl radical is practically unaffected by the presence of acrylate in concentrations up to 0.1 M." ° However, one can obtain only estimations of kinetic rate constants A add... 

A significant number of works are concerned with the development of new membranes for the separation of mixtures of aromatic/alicyclic hydrocarbons [10,11,77-109]. For example, the following works can be mentioned. A mixture of cellulose ester and polyphosphonate ester (50 wt%) was used for benzene/cyclohexane separation [113]. High values of the separation factor and flux were achieved (up to 2 kg/m h). In order to achieve better fluxes and separation factors the attention was shifted to the modification of polymers by grafting technique. Grafted membranes were made of polyvinylidene fluoride with 4-vinyl pyridine or acrylic acid by irradiation [83]. 2-Hydroxy-3-(diethyl-amino) propyl methacrylate-styrene copolymer membranes with cyanuric chloride were prepared, which exhibited a superior separation factor /3p= 190 for a feed aromatic component concentration of 20 wt%. Graft copolymer membranes based on 2-hydroxyethyl methylacrylate-methylacrylate with thickness 10 pm were prepared [85]. The membranes yielded a flux of 0.7 kg/m h (for feed with 50 wt% of benzene) and excellent selectivity. Benzene concentration in permeate was about 100 wt%. A membrane based on polyvinyl alcohol and polyallyl amine was prepared [87]. For a feed containing 10 wt% of benzene the blend membrane yielded a flux of 1-3 kg/m h and a separation factor of 62.

The use of tributylboron as an initiator which bonds acrylic monomers to dental tissue has been advocated by Masuhara for some time (28). His "Enamite" - a solution of 2-hydroxy-3-beta-naphthoxy-propyl methacrylate, methyl methacrylate, poly(methyl methacrylate), and tri-n-butylboron - is said to show unusually high adhesion to enamel, and, reduced occlusal caries (29). This system has also been used in orthodontics for binding brackets to the frontal face of teeth.
