Title: Soluble and fusible polymers and copolymers of p-and/or m-diisopropenylbenzene and a method of preparing the same
IPC: C08F2/00
Filed: 1964-09-04
Abstract: Soluble and fusible polymers of di-isopropenyl benzene are made by effecting the polymerization in the presence of an organolithium catalyst and (a) an oxy-alkylated monohydric mononuclear or polynuclear phenol and/or (b) an oxyalkylated polyhydric mononuclear or polynuclear phenol and/or (c) polyglycols of the general formula HO-CH2(CH2-O-CH2)n-CH2OH in which n is greater than 5, and which may be etherified or esterified.  The polymerization may be started at a temperature greater than +10 DEG  C. and continued at a temperature below +10 DEG  C. The polymerization may be effected in the presence of other monomers such as styrene, alpha-methystyrene, 1-isopropyl-4-isopropenyl benzene, acenaphthylene, vinyl pyridene methacrylic acid esters, acrylonitrile, or butadiene. The polymerization is preferably effected in a solvent such as benzene, toluene, heptane, xylene, or cumene.  Exemplified monomers are p-di-isopropenylbenzene, m-di-isopropenyl benzene, mixtures of m and p-diisopropenyl benzene, a mixture of styrene and m-diisopropenylbenzene, a mixture of alphamethylstyrene and p-diisopropenylbenzene, a mixture of methylmethacrylate and p-diisopropenylbenzene, a mixture in which the acrylate is replaced by butadiene, a mixture in which butadiene is replaced by vinylpyridene, a mixture of p-diisopropenylbenzene and acenaphthylene, a mixture of p-diisopropenylbenzene and acrylonitrile, a mixture of p-diisopropenyl and 1-isopropyl-4-diisopropenylbenzene, and a mixture of diisopropenylbenzene and methylpentadiene.  The polymers are recovered by treating the polymerizate with methanol containing acetic acid, washing the product with methanol, and drying under vacuum.  The polymers may be converted to the hard, infusible state by heating if desired, in presence of a peroxide.

In a method of welding together thermoplastic synthetic resin components a welding agent capable of fusing with the surfaces of the components is injected under pressure between the surfaces through an aperture into a closed space defining the weld and formed at least in part by the surfaces of the weld. The welding agent may be a synthetic plastic fluidized either by heat at a temperature higher than the softening temperature of the plastic surfaces or by a chemical solvent and in the latter case may contain an excess of the solvent so as to unite the components. In one embodiment, Fig. 1, an accumulator housing 1 is supported by a flange 3 thereon on a frame 7. A cover 2 is held in position by a pressure-plate 9 having a metal frame 10 secured thereto. The welding agent, which may contain a dye, is injected from a nozzle 14 through bores in the plate 9 and the frame 10 into a closed channel 11, the plate 9 and the frame 10 being removed when the joint has hardened. In a modification, Fig. 2, a channel 23 into which the agent is injected through channels 24 is formed exclusively in the components 21, 22 and may be provided with branches normal to the connecting zone of the components. In an alternative embodiment, Fig. 3, a methacrylic resin cover 30 of a motor vehicle signalling lamp is secured to a reflector plate 31 of similar resin and an ornamental metal strip 32 is inserted into the joint prior to welding. The strip may be omitted and the agent may contain a dye or metal powder, the latter to render the weld electrically conductive.
