    摘要： The invention concerns a method for producing a superhydrophobic membrane or surface coating of a substrate from an aqueous phase comprising the following steps: a) Preparing an aqueous dispersion by dispersing particles of hydrophobic polymer(s) in an aqueous solution of protic polymer(s), wherein the protic polymer(s) and the hydrophobic polymer(s) are present in a weight ratio of protic polymer(s):hydrophobic polymer(s) in a range of 5:95 to 22:78, b) electrospinning the dispersion of step a) onto a carrier for producing the membrane or onto the surface for producing the surface coating thereby producing at least one fiber and a nonwoven fabric from the fiber, c) subjecting the nonwoven fabric to a sol-gel process, wherein a precursor/precursors of the sol-gel comprise(s) an alkoxysilane, and d) curing the nonwoven fabric obtained by step c) at a temperature in a range of 50° C. to 150° C.

    摘要： Blends of polymeric materials comprising a plurality of substantially random interpolymers each interpolymer comprising:(1) from about 1 to about 65 mole percent of polymer units derived from either(a) at least one vinyl aromatic monomer or(b) at least one aliphatic or cycloaliphatic vinyl or vinylidene monomer, or(c) a combination of at least one vinyl aromatic monomer and at least one aliphatic or cycloaliphatic vinyl or vinylidene monomer, and(2) from about 35 to about 99 mole percent of polymer units derived from ethylene and/or at least one aliphatic alpha olefin having from 3 to 20 carbon atoms; and wherein:the amount of polymer units derived from vinyl aromatic monomer and/or aliphatic or cycloaliphatic vinyl or vinylidene monomer in any interpolymer component differs from that amount in another interpolymer component by at least 0.5 mole percent.These blends of interpolymer components give enhanced properties or processability when compared to the individual polymers comprising the blend.

    摘要： The graded-index optical transmission medium with a low transmission loss, a favorable index distribution and superior in softness etc. can be constituted by a mixture of polymers Pn having different refractive indices and by restricting the attenuation L.sub.F of the medium in accordance with the below inequality (I).The medium may advantageously be produced by way of admixing a thermoplastic polymer (A) and a monomer (B) able to form a polymer mutually soluble with the polymer (A), molding the mixture and volatilizing the monomer (B) from the surface of thus shaped substance. ##EQU1## wherein Wn are the respective proportions by weight of mixing of the polymers Pn to the whole of the mixture of the polymers Pn, and ##EQU2## Wn is equal to one.
