Embodiment 2

[0055] Example 1 was repeated except that Ropaque TM Alkali-swellable Hollow Sphere Polymer Ropaque for HP1055 TM AF1055 (manufactured by Rohm and Haas, Philadelphia, PA) instead.

Embodiment 3

[0057] Example 1 was repeated except that Ropaque TM HP1055 was replaced by fixed base-swellable, cross-linked hollow sphere polymer sample A. Specimen A passed in Ropaque TM AF1055 is obtained by adding 4% divinylbenzene during polymerization.

[0058] Table 1

[0059]

[0060] Alkali-swellable hollow sphere polymers show better opacity at and above curing temperatures (approximately 150 °C) commonly used for woven fabric and woven applications, which indicates that at high temperatures, it is compatible with volatile base-containing hollow spheres. Polymers have increased utility compared to As shown by the test results, the use of difunctional monomers allowed the drying and curing of the polymer films to proceed at higher temperatures without loss of opacity.

Embodiment 5

[0064] Example 4 was repeated except that the hollow sphere polymer Ropaque swelled with a fixed base TM AF1055 instead of Ropaque TM HP 1055.

Abstract

A method is disclosed using a heat resistant hollow sphere polymer having a core layer swollen with a hard or fixed base, the hollow sphere polymer being applied at a temperature of 100°C to 350°C. Articles made by the method are also disclosed.

Description

technical field [0001] The present invention relates to a method of using heat resistant hollow sphere polymers having a core layer swollen with a hard or fixed base, which hollow sphere polymers are subjected to temperatures between 100°C and 350°C in use. Background technique [0002] Porous, or hollow, polymeric particles are generally prepared by swelling multilayer polymers having a core and a shell to form one or more voids within the interior of the hollow polymeric particle. The use of such hollow polymer particles to provide useful properties such as brightness, whiteness, opacity and / or low density is well known in the art. In many cases, the use of hollow polymer particles reduces the cost of the final product by replacing or diluting pigments, some of which are expensive (eg, titanium dioxide). Hollow polymer articles are frequently used in paints, coatings, inks, sunscreens, paper manufacturing, and several other fields. However, their use is often limited to ...
