    摘要: The present invention is directed toward an absorbable crystalline segmented copolymer comprising a polyalkylene succinate segment end-grafted in a single-step with a mixture of monomers comprising caprolactone, l-lactide, and/or glycolide. The present invention is also directed toward an absorbable crystalline segmented copolymer arising from a trihydroxy compound that is reacted in a single-step with a mixture of monomer comprising ε-caprolactone, l-lactide, and/or glycolide to produce monocentric polyaxial polymers.

    摘要: A composition and method for forming investment casting shells includes using colloidal silica, zircon flour, and fused silica in a slurry which is applied to a pattern. After the slurry is applied to the pattern, it is allowed to partially or completely solidify. After the shell has solidified, the pattern may be melted or otherwise removed. A molten material is introduced into the shell and allowed to cool to form an article. Finally, the shell is broken away or otherwise removed from the article. The improved shell slurry composition and corresponding method minimizes pattern-to-pour cycle times and is environmentally friendly.

    摘要: A process for preparing dermatan sulphate (DS) of pharmaceutical purity from animal organs rich in mucopolysaccharides (MPS), by: (a) stabilizing the fresh organs by freezing them either as such or in the form of powder, (b) micronizing the material containing the MPS with an aqueous CaCl.sub.2 solution, (c) digesting the homogenate comprising the raw material and the CaCl.sub.2 with proteolytic enzymes at alkaline pH and at low temperature, (d) acidifying, heating and filtering the lysate, (e) treating the filtrate with quaternary ammonium salts able to undergo complexing with and thus precipitate either the DS along or all the MPS selectively, (f) recovering and purifying the DA either directly from the ammonium salt complex containing it or from the complex obtained from the mixture of ammonium salt complexes of all the MPS by fractional solubilization with acetone.
