    摘要: The invention relates to mouldings comprising a transparent plastic matrix with small proportions of incorporated, very finely divided plastic particles which have a particle diameter less than the wavelength of visible light, and to the use of these mouldings for visualizing laser beams and for illumination purposes.A refractive index difference between the core of the scattering particles B and the matrix plastic A in the range 0.09-0.3 and a good distribution of the plastic particles B in the matrix are important for high transparency of the mouldings according to the invention in combination with good visualization of laser beams.The plastic particles B are core-shell particles, as are readily obtainable by emulsion polymerization (cf. for example DE 198 20 302).

    摘要: Modified rubber compositions comprise by weight about 15-60% of a highly saturated aliphatic rubber such as ethylene-propylene-diene rubber, about 25-80% of acrylate monomer units; and less than about 5% multi-functional monomer units. The compositions exist as amorphous heterogeneously dispersed phases. The first phase comprises the copolymer rubber to which polymers of at least 10% of the other monomer units are grafted. The second phase comprises the other monomers polymerized as homo and copolymers, not grafted to the rubber. Optionally, up to 20% of the composition comprises high index monomer units. The high index monomer units may be copolymerized with the acrylate and grafted to the rubber. Greater than 10% of the monomer units other than rubber are grafted to the rubber. The number average molecular weight of the grafts is between 10,000 and 80,000 daltons. About 2-20% by weight of one or more polymers may be provided to adjust the refractive indices of the rubber or the polyacrylate phase in the final product such that when the composition is present at the 10% rubber level, the haze can be reduced to less than 20%.
