摘要： Terpolymers comprising propylene and small amounts of ethylene and butene-1 are made in a two-stage process wherein a relatively high melting random terpolymer is made in a first stage and a relatively low-melting random terpolymer incorporating a higher concentration of ethylene, is made in a second stage so that it is dispersed in the product of the first stage. The two process stages may be operated in a single batch reactor or two continuous reactors in series.
摘要翻译：包含丙烯和少量乙烯和丁烯-1的三元共聚物是在两阶段方法中制备的，其中在第一阶段制备相对高熔点的无规三元共聚物，并制备掺入较高浓度乙烯的相对低熔点的无规三元共聚物在第二阶段中使其分散在第一阶段的产品中。两个工艺阶段可以在单个间歇反应器或两个串联的连续反应器中操作。

摘要： Impact resistant compositions are prepared by the incorporation of acrylic rubber particles (or multi-stage emulsion polymer particles containing a rubbery layer) in a predominantly methyl methacrylate matrix. The emulsion particles are prepared in water as a latex stabilized with anionic groups. The particles are transferred to a methyl methacrylate medium by destabilizing the latex with a quaternary ammonium salt and optionally a di- or multivalent inorganic salt. Impact resistant compositions are prepared by separating the water from the methyl methacrylate layer and polymerizing the methyl methacrylate.
摘要翻译：抗冲击组合物通过在主要甲基丙烯酸甲酯基质中引入丙烯酸橡胶颗粒（或含有橡胶层的多阶段乳液聚合物颗粒）来制备。乳液颗粒在水中制备为用阴离子基团稳定的胶乳。通过使季铵盐和任选的二价或多价无机盐不稳定胶乳将颗粒转移到甲基丙烯酸甲酯介质中。通过从甲基丙烯酸甲酯层分离水并聚合甲基丙烯酸甲酯来制备耐冲击组合物。

摘要： Particle size, swelling, and other characteristics of unsaturated polyester beads are controlled in a suspension polymerization system to make beads suitable for use as fillers in molding and forming. Process steps include degassing prior to polymerization, positive pressure during polymerization, and washing to remove suspending agent.

摘要： On improved transformation method uses an initial set of Hidden Markov Models (HMMs) trained on a large amount of speech recorded in a low noise environment R to provide rich information on co-articulation and speaker variation and a smaller database in a more noisy target environment T. A set H of HMMs is trained with data provided in the low noise environment R and the utterances in the noisy environment T are transcribed phonetically using set H of HMMs. The transcribed segments are grouped into a set of Classes C. For each subclass c of Classes C, the transformation &PHgr;c is found to maximize likelihood utterances in T, given H. The HMMs are transformed and steps repeated until likelihood stabilizes.
