    摘要： An adhesive composition comprising a mixture of water based polymer in latex form and a material generally referred to as a thickening agent is disclosed for removably adhering a product to a substrate, for example a carpet with an attached backing to a flooring substrate. The adhesive may be applied as a layer to the carpet backing, dried and subsequently activated with water to adhere the carpet to the floor. After drying, the adhesive layer may be reactivated with water to permit the carpet to be removed from the floor. The adhesive layer when dried on the surface of a latex foam backed carpet provides a non-tacky surface which additionally increases the abrasion resistance of the latex foam backing thereby reducing damage to the backing during normal storage and handling.

    摘要翻译： 公开了一种粘合剂组合物，其包含胶乳形式的水基聚合物和通常称为增稠剂的材料的混合物，用于将产品可移除地粘附到基材上，例如具有附着背衬的地毯与地板基材。 粘合剂可以作为层施加到地毯背衬上，干燥并随后用水活化以将地毯粘附到地板上。 干燥后，可以将粘合剂层与水再活化，以使地毯从地板上移除。 在胶乳泡沫背衬地毯的表面上干燥时的粘合剂层提供了非粘性表面，其另外增加了胶乳泡沫背衬的耐磨性，从而在正常的储存和处理期间减少对背衬的损害。

    摘要： Vesicular recording materials include a sensitized layer which comprises a polymeric vehicle for the sensitizing agent which is a copolymer of 62 to 95 mole % of acrylonitrile or a derivative thereof with acrylamide or a derivative thereof. Preferred copolymers are derived from acrylonitrile and N-tert.butyl acrylamide or diacetone acrylamide. The sensitized layers may contain a surfactant and may be subjected to water treatment.

    摘要： Tough transparent thermoplastics blends may be prepared by blending 10 to 99 weight percent of a block copolymer; 0.1 to 1 weight percent of particulate rubber having a particle size from 0.1 to 10 microns; and the balance a clear glassy polymer. These clear polymers are useful in a number of applications, particularly for those applications requiring quite high toughness and transparency such as packaging, containers or protective covering.

    摘要： Vesicular recording materials are described which include a sensitized layer comprising a polyeric vehicle for the sensitizing agent which is an acrylonitrile/substituted or unsubstituted styrene copolymer with at least 55 mole % of acrylonitrile and preferably less than 85 mole %. The copolymer is usually homogeneous and preferably derived from acrylonitrile and the styrene comonomer along and most preferably contains from 65 to 82 mole % of acrylonitrile. The copolymer is softenable on heating to permit the gas released by the sensitizing agent in the light struck areas to form light-scattering or reflecting vesicles therein.A surfactant in an amount of at least 1% by weight, based on the weight of the copolymer, is essential to vesiculation and anionic surfactants are especially effective in providing a wide tonal range and good speed rating, amounts up to 20% by weight being preferred. Generally, amounts of the surfactant in the range 2 to 5% by weight provide a satisfactory combination of vasiculating properties. The sensitized layer is preferably applied as a coating to a carrier sheet support such as a polythylene terephthalate film. These recording materials have excellent vesiculating properties, particularly tonal range and speed rating.
