PROCESS FOR PREPARING A GRANULAR OXYMETHYLENE POLYMER, AND FORMED PRODUCTS MADE FROM THE POLYMERS OBTAINED SO.of the disclosure: Granular oxymethlene polymers are prepared by cooling a solution or dispersion of an oxymethylene polymer, the temperature of the said solution of dispersion polymer, to a...
1,3-Butadiene is a colorless gas at room temperature and is liquid at a few degrees below water's freezing point. It is typically extracted from the C4 cut of an olefins cracking process but can be made through dehydrogenation of normal butane. 1,3-Butadiene is used mainly to make synthet...
andmethane. The first living cells probably evolved from these complex molecules (seelife: Production of polymers). For example, the accidental joining (condensation) of theamino acidglycineand thefatty acidacetatemay have formed complex organic molecules known asporphyrins. These molecules, in turn,...
Styrene-based polymer moldings with a crystallinity of at least 20% obtained by subjecting moldings of crystalline styrene-based polymers having mainly syndiotactic configuration to heat treatment at a temperature of 120 to 270 DEG C. These moldings are excellent in physical properties such as heat ...

Polypropylene (PP) or polyoxy-methylene (POM) are the standard materials used for the bearing rings, but other polymers are also possible on request. Balls can be made from polymer, stainless steel, glass or other materials. Cages are made from polyamide or polypropylene. Polymer ball bearings...
there are certain end uses and products made from polymers and resins which desirably possess the properties of more than one polymer or resin. Certain properties can be added to the inherent properties of the polymer or resin by a wide variety of techniques. However, all such known techniques...
