Back-polymerization of photopolymers with application in e.g. dental fillings, occurs at interface opposite entry point, where coating converts incident radiation to new wavelengths initiating setting

The polymer is irradiated by an electromagnetic wave. Its spectral band is unsuitable to initiate polymerization. Only following a change in wavelength resulting from incidence of the beam on the side of the polymer opposite the location of beam entry, is polymerization initiated. An Independent claim is included for corresponding equipment. Preferred features: Contact surfaces are treated before coating the polymer, to emit waves exciting polymerization. Radiation emitted from the far side (opposite the entry point) is employed for photopolymerization. Reversal of directed polymerization shrinkage prevents formation of edge gaps or internal stressing due to polymerization. After-flow compensates polymerization shrinkage, with the same benefits. Photoinitiators used in the polymer are matched or co-ordinated with substances on the contact surfaces, used to shift the wavelength. Before coating the contact surfaces with polymer, they are treated with substances emitting at wavelength exceeding excitation wavelength, in accordance with Stokes rule. Radiation-emitting substances at contact surfaces, function as bonding agents between polymer and adjacent materials. Radiation emission at contact surfaces serves for optical marking of boundaries between polymer and bordering materials.

Endoprosthesis insert

The invention relates to medicine, and more particularly to antifriction inserts made of modified polytetrafluoroethylene for artificial endoprostheses of joints, and can be used in friction assemblies of endoprostheses of hip, knee, shoulder and elbow joints and also intervertebral discs. The insert is a component with a curvilinear surface and is formed from modified polytetrafluoroethylene. The starting blanks are processed with high-energy ionizing radiation (alpha radiation, electron radiation, irradiation with protons, neutrons and other ionizing particles, gamma bremsstrahlung and gamma radiation). The processing is carried out at a temperature strictly higher than the melting point of the crystal phase of a polymer in an oxygen-free atmosphere. The processing is carried out, in particular, with the aid of an electron accelerator generating gamma bremsstrahlung up to an absorbed dose of 0.5-500 kGy or equivalent in terms of energy for high-energy coherent radiation. In the irradiation process, the polymer temperature is reduced by no more than 0.5 °С/10 kGy. After the processing with ionizing radiation, the polymer is subjected to thermal processing. The result consists in reducing the destruction of sections of the polymer, in reducing the wear rate and in extending the service life of the insert.

Apparatus and method for producing stereo-regular polymers

Stereo-regular polymers are produced by forming a moving stream of gaseous monomer having an electric dipole moment, irradiating the monomer with monochromatic light of a wavelength suitable for activating it, and orientating the activated monomer in an electric field. The activated, orientated monomer then polymerizes to form a stereo-regular polymer. Alternatively, a monomer of the general formula ##STR1## can be used, where at least one of the R groups, the resonating R group, forms an electric dipole moment with the remainder of the monomer. The monomer is then irradiated with a monochromatic light beam having a frequency which resonates with a harmonic frequency resulting from the bond between the resonating R group and the remainder of the monomer. Activation of that particular bond on that particular type of monomer results in a stereo-regular polymer. For best results, however, the two methods are combined.

931,368. Restoring photopolymerizable elements. E. I. DU PONT DE NEMOURS & CO. Nov. 29, 1961 [Jan. 13, 1961], No. 42777/61. Class 98 (2). Elements comprising a support with a solid stratum of macromolecular polymer binding agent, an unsaturated compound with at least one terminal ethylenic group and a polymerization initiator therefor, of the general nature of those of Specification 741, 294 and having the purpose of relief printing plate production by imagewise exposure and removal of unpolymerized portions of the stratum, but which have lost photographic speed by absorption of molecular oxygen, have such speed restored by overall exposure to actinic radiation. After this the imagewise exposure and removal treatment should be effected within an hour. Examples are directed to production of the elements, artificial ageing by storing in air and comparisions of results from these before and after pre-exposure, with particular references to the matter of undercutting of the relief images produced. Additionally, numerous materials for forming the strata are listed and a restoring process by conditioning in an inert atmosphere is described.
