摘要： The properties of (meth)acrylic ester/(meth)acrylic acid copolymer webs, such as films and nonwovens, are improved by blending the ester/acid copolymer with a modified polyolefin, such as an ethylene/(meth)acrylic acid copolymer and/or a styrene/butadiene block copolymer, and a polyether block amide copolymer. The copolymer blend provides a polymeric material which is useful for making personal care products such as diapers and feminine pads in that it can be made water-soluble in alkaline solutions while exhibiting other properties which are necessary for adequate product performance. Such materials are also useful for packaging products, such as film for plastic bags and the like.

摘要： A laser-sinterable powder product has been prepared having unique properties which allow the powder to be sintered in a selective laser sintering (SLS) machine to form a sintered part which is near-fully dense. For most purposes, the sintered part is indistinguishable from another part having the same dimensions made by isotropically molding the powder. In addition to being freely flowable at a temperature near its softening temperature, the powder has a two-tier distribution in which substantially no primary particles has an average diameter greater than 180.mu.m, provided further that the number average ratio of particles smaller than 53.mu.m is greater than 80%, the remaining larger particles being in the size range from 53.mu.m to 180.mu.m. When the powder is a semicrystalline synthetic resin having a number average molecular weight in the range from about 30,000 to 500,000; a molecular weight distribution M.sub.w /M.sub.n in the range from 1 to 5; and, provides a window of sinterability in the temperature range from near the powder's softening temperature T.sub.s to its caking temperature T.sub.c, it is sintered layer-upon layer to form a near-fully dense part of arbitrary shape.

For most purposes, the sintered part is indistinguishable from another part having the same dimensions made by isotropically molding the powder.

A powder with slow recrystallization rates, as evidenced by non-overlapping endothermic and exothermic peaks in their differential scanning calorimetry characteristics for scan rates of on the order of 10.degree. C. to 20.degree. C. per minute, will also result in sintered parts that are near-fully dense, with minimal dimensional distortion.

摘要： This invention is concerned with producing glycols of the formulaHOCHRCH.sub.2 OHfrom hydrolysis, in a homogeneous liquid phase mixture, of an alkylene carbonate of the formula ##STR1## in which R is either hydrogen or methyl. This is accomplished by using an amount of water in excess of stoichiometry and using potassium carbonate as the preferred catalyst. The reaction is effected under a carbon dioxide pressure of at least 80 psig and the reaction temperature is desirably between about 85.degree. C. and 500.degree. C.

摘要： This method teaches how to recover and reuse a powder of a thermally degradable material which is used in a selective laser sintering (SLS) process. To recycle such a laser-sinterable powder successfully in a SLS machine it is protected against degradation by cooling the hot bed while layer-upon-layer (layer-wise) of powder is being sintered, seriatim, to form successive slices fused together to form an article of arbitrary shape (part). The process requires maintaining the powder which has more than 80% of the number of particles
摘要翻译：该方法教导了如何回收和再利用用于选择性激光烧结（SLS）工艺的可热降解材料的粉末。为了在SLS机器中成功地回收这样的可激光烧结粉末，通过冷却热床来保护其免受降解，同时层压（层）上的粉末被烧结，形成连续的切片，以形成熔合在一起形成任意形状的文章（部分）。该方法需要将具有超过80％的颗粒数量（m 3）的颗粒保持为静止床，其仍然是足够多孔的，以允许冷却气体向下流动穿过床而不破坏其表面。由于每个切片形成在表面，并且部件在其形成时被支撑在绝热的床中，与切片相邻的粉末的温度比床的其余部分中的粉末高得多，但是对于冷却气体，会过热。过热粉末不仅会降解，而且会熔化到热部件的表面，形成“成长”，从而使零件不能用于其预定目的。该方法允许经济地将未使用的粉末从床中回收到灭绝。如果粉末在热时也对氧气敏感，则使用惰性气体作为冷却气体。

摘要： This invention relates to crosslinker sytems for polyurethanes and a process for producing such polyurethane products. The polyurethanes are prepared by reacting an organic polyisocyanate with an organic compound having active Zerewitinoff hydrogen atoms, e.g., a polyol with an alkoxylated diethyltoluenediamine crosslinker. Improved properties can be achieved, such as, higher load-bearing at equivalent density; higher tear; and higher elongation.
