Poly acrylates processing conditions

Fanta, G.F., Swanson, C.L. and Shogren, R.L. (1992) Starch-poly(ethylene-co-acrylic acid) composite films. Effect of processing conditions on morphology and properties. Journal of Applied Polymer Science, 44, 2037-2042. [Pg.31]

The various types of poly(acrylates) are initially prepared as mesogenic-like monomers in a similar manner to low molar mass liquid crystals. The acrylate group is usually located at a terminal position of the mesogenic monomer (195), which is polymerised (Scheme 48) in a radical process by using an initiator (e.g., AIBN or hydrogen peroxide) under thermal conditions or by photo-induction to generate a liquid crystalline poly(acrylate) (196). [Pg.181]

Usually, only intercalated structures with low poly(styrene sulfonate), poly(vinyl sulfonate), poly(acrylic acid), poly(ethylene oxide), and dioctyl sulfosuccinate LDH nanocomposites.Thermoplastic nanocomposites based on LDH are usually prepared by solution intercalation or in situ polymerization. In our previous work we showed that it is also possible to get delamination of LDH in thermoplastic polymers by melt compounding when a suitable inter-or intralayer composition of LDH and proper processing conditions are selected. ... [Pg.256]

Similar effects of RESS processing conditions on product morphology were observed by Mawson et al. in their preparation of fibers and particles of a crystalline fiuoropolymer, poly(l,l,2,2-tetrahydroperfluorodecyl acrylate) via the rapid expansion of supercritical CO2 solution (83). Shown in Figure 6 are... [Pg.504]

Anionic polyacrylamide was prepared by gamma radiation-initiated copolymerization of acrylamid with sodium acrylate in aqueous solution at optimum conditions for the copolymerization [17]. The copolymerization process produces water-soluble poly (acrylamide-sodium acrylate [pAM-AANa] of high molecular weight [17,54]. [Pg.120]

Stoy and co-workers (2) reported an approach that used alternative materials and involved the partial hydrolysis of poly(acrylonitrile) to form a complex structure that was presumed to involve sequences of unhydrolyzed poly(acrylonitrile) interspersed with acrylamide and acrylic acid sequences that resulted from hydrolyzed nitrile groups. Crystallites of unhydrolyzed poly(acrylonitrile) provided the physical cross-link domains within a matrix of the water-swellable portions of the structure. The tensile properties for such materials were considerably enhanced in comparison to the conventional covalently cross-linked hydrogels, and the absence of cross-links allowed processing under certain conditions. [Pg.62]
