    • Embodiments of the present invention comprise biodegradable composites including a polyurethane component and cells encapsulated in gel beads, as well as methods of making such composite and uses thereof. In certain embodiments the gel beads are alginate beads. The composites may be moldable and/or injectable. After implantation or injection, a composition may be set to form a porous composite that provides mechanical strength, supports the in-growth of cells, and/or delivers cells to particular tissues. Inventive composites have the advantage of being able to fill irregularly shaped implantation sites, deliver cells in a localized and noninvasive manner, and optimize cell proliferation and differentiation of delivered cells.
    • 本发明的实施方案包括包含聚氨酯组分和包封在凝胶珠中的细胞的生物可降解复合材料,以及制备这种复合材料及其用途的方法。 在某些实施方案中,凝胶珠粒是藻酸盐珠粒。 复合材料可以是可模塑的和/或可注射的。 在植入或注射后,可以将组合物设置成形成提供机械强度的多孔复合材料,支持细胞的生长和/或将细胞递送到特定组织。 本发明的复合材料具有能够填充不规则形状的植入位点,以局部和非侵入性方式递送细胞并优化递送细胞的细胞增殖和分化的优点。

    • This invention relates to ethylenically unsaturated macromers which contain reactive unsaturation, and to a process for preparing these ethylenicallly unsaturated macromers which contain reactive unsaturation. The process of preparing these ethylenically unsaturated macromers comprises reacting a monofunctional compound which corresponds to a specific formula with at least one alkylene oxide, in the presence of at least one alkoxylation catalyst. The ethylenically unsaturated macromers correspond to the formula set forth herein. This invention also relates to preformed stabilizers comprising ethylenically unsaturated macromers, to a process for preparing these preformed stabilizers, to polymer polyols comprising these preformed stabilizers, and to a process of preparing these polymer polyols which comprise these preformed stabilizers. Polymer polyols comprising ethylenically unsaturated macromers and a process for their preparation are also described.
    • 本发明涉及含有反应性不饱和键的烯键式不饱和大分子单体,以及制备这些具有反应性不饱和度的烯属不饱和大单体的方法。 制备这些烯属不饱和大分子单体的方法包括在至少一种烷氧基化催化剂的存在下使对应于特定式的单官能化合物与至少一种烯化氧反应。 烯键式不饱和大分子单体对应于本文所述的式。 本发明还涉及包含烯属不饱和大分子单体的预制稳定剂,制备这些预型稳定剂的方法,包括这些预制稳定剂的聚合物多元醇,以及包含这些预型稳定剂的这些聚合物多元醇的制备方法。 还描述了包含烯属不饱和大分子单体的聚合物多元醇及其制备方法。
