摘要： The invention relates to thermosetting compositions which are blends of novel poly(arylacetylenes) and, as fluidizers, certain aromatic organic compounds containing at least two aromatic rings. The poly(arylacetylenes) are prepolymers of polyacetylenically substituted aromatic compounds, which prepolymers have a number average molecular weight of from about 900 to about 12,000 and contain from about 5 to about 20% by weight of acetylenic groups. Diethynylbenzene is one of the preferred monomers used in preparation of the prepolymers. Representative of the compounds containing at least two aromatic rings are triphenylphosphine and triphenylphosphine oxide. The compositions are curable by heat to produce thermoset resins which have very desirable physical properties at both normal and high temperatures.

摘要： A method of injection molding wherein a pair of separable mold plates are initially urged together and fluid plastic is injected into a mold cavity formed between the mold plates to form an article. The injection pressure of the fluid plastic is utilized to generate forces sufficient to overcome the internal forces urging the mold plates apart and thus hold the mold plates together until the material being molded solidifies either by cooling, chemical reaction or phase change.
摘要翻译： 一种注射成型方法，其中一对可分离的模板最初被推动在一起，并且将流体塑料注入形成在模板之间的模腔中以形成制品。 流体塑料的注射压力用于产生足以克服推动模具板分开的内力的力，从而将模板保持在一起，直到模制材料通过冷却，化学反应或相变而固化。
