摘要： A thermoplastic benzophenone polyester consisting essentially of recurring units of the formula: ##STR1## having an intrinsic viscosity of at least 0.85 deciliter/gram as measured in 1:1 phenol/tetrachloroethane at 25.degree. C, is useful for making shaped articles having high impact strength.A process for preparing a thermoplastic polyester according to the above formula is also described which comprises the steps of (a) adding a solution of 4,4'-benzophenonedicarboxylic acid halide in an inert, water-immiscible organic solvent to a basic aqueous solution of a salt of 2,2-bis(4'-hydroxyphenyl)propane to form and precipitate the polyester during the addition and (b) recovering the precipitated polyester.There is also provided a shaped article prepared from the polyester having an impact strength of at least about 2 ft.lb./in. of notch as measured by the Izod impact test, ASTM D-256-56.

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.
