    摘要： A monomeric aromatic dicyanate is purified to remove color forming impurities, combined with a zinc salt catalyst and cured first below 200.degree. C. and then for a limited time at or above 200.degree. C., either alone or in admixture with or on a thermoplastic polymer. For example, purified 2,2-bis(4-cyanatophenyl)propane is purified, combined with a poly(ester carbonate) and zinc chloride, and then cured at increasing temperatures from 150.degree. C. to 250.degree. C.

    摘要： Purified aromatic dicyanates are cured with a catalyst which is an Mn(II), Ag(II), Fe(III), Bi(III), In(III) or Hf(IV) salt at 150.degree.-200.degree. C. and then at 200.degree.-300.degree. C. for a time sufficient to cure the dicyanate without causing color formations to the extent of a Yellowness Index over 30. In some forms the dicyanate is combined with the catalyst and a thermoplastic.

    摘要： By poststretching, at a temperature between about 135.degree. and 160.degree. C., a polyethylene fiber, which has already been oriented by drawing at a temperature within 5.degree. C. of its melting point, an ultra high modulus, very low creep, low shrink, high tenacity polyolefin fiber having good strength retention at high temperatures is obtained. The poststretching can be in multiple stages and/or with previous annealing. The poststretching should be done at a draw rate of less than 1 second.sup.-1. Tensile modulus values over 2,000 g/d for multifilament yarn are consistently obtained for ultrahigh molecular weight-polyethylene, with tensile strength values above 30 g/d while at the same time dramatically improving creep (at 160.degree. F. (71.1.degree. C.) and 39,150 psi load) by values at least 25% lower than fiber which has not been poststretched. Shrinkage is improved to values less than 2.5% of the original length when heated from room temperature to 135.degree. C. Performance at higher temperature is improved by about 15.degree. to 25.degree. C.

    摘要： The present invention is a flexible impact resistant article comprising a plurality of prepreg packets. Each prepreg packet comprises at least about 2 prepreg layers. Each prepreg layer comprises a plurality of coplanar fibers embedded in a polymeric matrix. There is a means to maintain at least a portion of each prepreg packet in successive layers. The prepreg packets are unattached to each other over a portion of their adjacent areas, preferably over a substantial portion of their adjacent areas. The plurality of packets results in improved flexibility.
