Abstract
1353391 Iridescent polymeric materials ZAIDAN-HOJIN OYO KOGAKU-KENKYUJO 19 April 1971 [31 March 1970] 25722/71 Heading C3P Iridescent polymeric materials comprise a three-dimensional closely-packed regularlyarranged structure of uniform polymeric microspheres having a particle diameter in the range 1500-4500 Š and derived from a polymeric latex having non-film-forming properties when dried below 60‹ C., the structure having been initially partially stabilized by heat treatment to form a structure in which the microspheres are fused to each other but retain their individual identity, and then completely stabilized by surrounding the microspheres with a polymeric material which has no measurable solubilizing effect on them and has a refractive index differing from that of the microspheres in absolute value to the extent of up to 0À1 to provide optical discontinuity. The materials are made by (1) allowing a suitable latex to stand in a quiescent state until iridescence is observed, whereby the particles of the latex become compacted and regularly arranged, (2) reducing the water content to below 5 wt. per cent while maintaining the state of quiescence, (3) filling the voids between the microspheres by impregnation with an inert liquid, e.g. liquid paraffin, liquid chlorinated paraffin, a mixture of diphenyl chloride and dibutyl adipate or an aqueous solution of sodium dodecyl sulphate, (4) heating the impregnated structure to impart mechanical stability thereto without destroying the regular arrangement thereof, (5) surrounding the compacted structure with suitable monomer(s), and (6) polymerizing the monomer(s), e.g. in the presence of benzoyl peroxide. In examples, the original latex is selected from:- styrene/divinyl benzene copolymer, polystyrene, styrene/methyl methacrylate, polyvinyl toluene, and methyl methacrylate/ divinyl benzene; and the following monomers and monomer mixtures are polymerized around. the compacted structure:-styrene/diallyl phthalate, methyl methacrylate/diallyl phthalate, methyl methacrylate / styrene / diallyl phthalate, methyl methacrylate and styrene. In Example 5, the iridescent material is coated with a polyvinyl alcohol film prior to the polymerization of monomers around it.
