摘要： A new vigor test is used to select seeds which, after appropriate polymeric coating, will perform well under adverse planting and growing conditions. For example, suitably coated hybrid corn seeds can be planted earlier than seeds now available, while still obtaining comparable or better yields. Particularly good results are obtained when seeds are coated with compositions comprising a side chain crystalline polymer and an amorphous polymer.
摘要翻译：新的活力测试用于选择在适当的聚合物涂层之后在不利的种植和生长条件下表现良好的种子。例如，适当涂覆的杂交玉米种子可以比现在可用的种子更早种植，同时仍然获得相当或更好的产量。当用包含侧链结晶聚合物和无定形聚合物的组合物涂覆种子时，可获得特别好的结果。

摘要： Systems and methods for delivering release materials, for example drugs and other bioactive materials. Crystalline polymeric systems, referred to as CYC carriers, are associated with the release materials, through chemical bonding or through physical association. The crystallinity of the CYC carriers results from the presence of crystallizable side chains, for example long chain n-alkyl moieties, which results in relatively low and sharp melting temperatures. One class of CYC carriers, referred to as CYSC polymers, have a majority of the crystallizable side chains pendant from the polymer backbone. Another class of CYC carriers referred to as ECC polymers, have a majority of the crystallizable side chains attached to terminal units of the polymer backbone. The ECC polymers can for example be obtained by modification of PLGA polymers. The CYC carriers in another class of non-polymeric. Some CYC carriers, referred to as CYC assemblies, have enhanced crystallinity as a result of the physical association of crystallizable moieties which are present in different types of molecule, for example between a polymer containing crystallizable moieties and a monomer containing crystallizable moieties. For some uses, particularly the delivery of drugs, a bioerodable CYC carrier is preferably used.

摘要： Novel modifying agents contain a sharply-melting crystalline polymer ingredient, preferably a side chain crystalline (SCC) ingredient, and an active chemical ingredient. Such modifying agents, especially when in the form of particles, can be placed in contact with a matrix, will not modify the matrix below the crystalline melting point Tp, but will rapidly modify the matrix above Tp. The active chemical ingredient can react with the matrix, catalyze a reaction of the matrix, or inhibit a reaction of the matrix. Particularly useful compositions are polymer precursors which are storage-stable at low temperatures but which are rapidly converted to crosslinked resins when heated to temperatures above Tp, optionally in the presence of light.

摘要： The rheological properties of a crosslinkable resin system are modified by the presence of a side chain crystalline (SCC) polymer (or a similar crystalline polymer which melts over a narrow temperature range). The polymer dissolves in the curable system at temperatures above the melting point of the crystalline polymer (Tp), but when the system is then cooled to a temperature below Tp, at least partially forms a separate phase in the curable system. Below Tp, this separate phase substantially increases the viscosity of the curable system (i.e. makes it thicker than the same system without the crystalline polymer). This is particularly valuable for sheet molding composites (SMCs) in which the increase in viscosity makes the composites less tacky, and for dry film resists (DFRs). Above Tp, the curable system containing the dissolved crystalline polymer has a viscosity which is substantially less than its viscosity below Tp.
摘要翻译：可交联树脂体系的流变性质通过侧链结晶（SCC）聚合物（或在窄温度范围内熔融的类似结晶聚合物）的存在而改性。聚合物在高于结晶聚合物（Tp）的熔点的温度下溶解在可固化体系中，但是当系统被冷却到低于Tp的温度时，至少部分地在可固化体系中形成单独的相。在Tp之下，该分离相基本上增加了可固化体系的粘度（即使其比没有结晶聚合物的相同系统厚）。这对于其中粘度增加使得复合材料较不粘性以及用于干膜抗蚀剂（DFR）的片状模塑复合材料（SMC）尤其有用。含有溶解的结晶聚合物的可固化体系在Tp之上的粘度基本上小于其粘度低于Tp的粘度。

摘要： Orthopedic casts which comprise an elastically deformed support which is held in its elastically deformed state by a solid casting composition. After the cast has been placed around a patient's limb, it is heated to soften the casting composition, thus permitting recovery of the cast into conforming contact with the limb. The support can for example be a fabric knitted from elastomeric fibers and glass fiber yarns. The casting composition can for example comprise polycaprolactone and/or a side chain crystallizable polymer, which melts at 45.degree.-60.degree. C. A padded liner can be placed between the cast and the limb. Recovery of the cast is preferably carried out by means of a hot air gun.

摘要： Shrinkage of cured resins is reduced by mixing the crosslinkable resin with a low profile additive (LPA). The LPA is in the form of particles which comprise an SCC polymer (or a similar crystalline polymer which melts over a narrow temperature range). The system is cured at a temperature above the melting point of the crystalline polymer (Tp), and the system and the LPA are such that at least part of the LPA remains as a separate phase in the curable resin at temperatures below Tp. It is believed that at least part of the crystalline polymer remains as a separate phase in the resin as it cures. Preferably at least part of the crystalline polymer forms a separate phase in the cured polymer after it has cooled.
