For cellulose nitrate, polyacrylates of higher alcohols have proved to give very smooth and transparent films. Good results are obtained with polybutyl acrylate and polyethylhexyl acrylate. The polyacrylates of higher alcohols can be used as plasticizers for rubber. Oligomers of acrylates can not be used in combination with PVC, because they give only hard films. [Pg.99]

Polarity of Vinyl Acrylic Latex and Surfactant Adsorption Contact angle measurements, dispersion and polar contribution to latex film surface tension and polarity of polymer calculated according to the method of Kaelble (10) of the three latex films are whown in Table V. It is seen that the polarity of the latex film decreases with increase in butyl acrylate content of the vinyl acrylic co-polymer. The polarity of the 70/30 (VA/BA) latex is very similar to that of the polybutyl acrylate homopolymer estimated to be about 0.21 (1). ... [Pg.234]

Chain transfer functionalization of cysteine was used by Brennan [4] to prepare macromonomer polybutyl acrylate end-functionalized with cysteine, (II), which was then polymerized with 4-aminobenzoic acid (111). [Pg.579]

To obtain better outdoor weatherability, polybutadiene rubber is frequently replaced as the substrate in impact polystyrene and ABS by EPDM, EVA (19). or polybutyl acrylate. Grafting of styrene. [Pg.223]

This work shows that, contrary to earlier reports of work conducted at low temperatures, substantial yields of liquid products are obtained on the high temperature degradation of the isomeric polypropyl acrylates and polybutyl acrylates. The products of the degradation reactions are identified and a comparison is possible with the results of studies of the polymers of the normal esters, i.e., methyl to butyl, the branched chain propyl, and the three branched butyl esters, all of the polymers having been examined under the same conditions.

Polybutyl acrylate is added to rigid polyvinyl chloride to increase impact strength. It is compatibilized by grafting polymethyl methacrylate onto it. [Pg.372]

Details are given of the influence of small crossbnked polybutyl acrylate particles as fillers on the diffusion rate of polybutyl methacrylate molecules in polybutyl methacrylate latex films. A fluorescence technique based upon direct nonradiative energy transfer was used to follow the diffusion. 39 refs. [Pg.53]

Swelling measurements were used to determine the extent of cross-linking of latex particles which had been prepared by emulsion polymerisation. Two latexes were investigated, a polybutyl acrylate and a polyisodecyl acrylate. With the latter, a comparison was made between the swelling behaviour of the fully crosslinked material... [Pg.103]

Polybutyl acrylate/polyglycidyl methacrylate core-shell latex was prepared by a two stage emulsion polymerisation. The formation of core-sheU morphology was confirmed by contact angle measuremoits. The impact properties of blends of polybutyl acrylate/polyglycidyl methacrylate core-shell composite particles with epoxy resin is discussed. 15 refs. [Pg.107]

The influence of light exposure on the photooxidative stability of aqueous acrylic-based latices was examined using FTIR and hydroperoxide analysis. The nature of impurities and oxidation products generated during manufacture of PMM A and polybutyl acrylate latices were characterised and inter-related to their influences on subsequent photooxidative degradation. 20 refs.

A study was made of the impact of incorporation of a small amount of carboxylic monomers (acrylic acid or methacrylic acid) into the latex particles in the limited flocculation process, often encountered in the semi-batch surfactant-free emulsion polymerisation of pure butyl acrylate. The possibility of producing carboxylated polybutyl acrylate latices with a smaller particle size was evaluated. The resultant latex was characterised to gain a better understanding of the effect of the surfactant-free technique on their physical properties, e.g. zeta potential, distribution of acrylic acid or methacrylic acid in the particles, and stability towards the added salt, compared with the conventional emulsion polymerisation system stabiUsed by surfactants. 35 refs.
