摘要： A polymerizable adhesive composition containing an olefinically functionalized carbohydrate, a polymerizable liquid monomer, and optionally at least one polymerization initiator or initiator system is described. The adhesive composition is particularly well suited for adhering plastic components as well as is preferably provided with sufficiently long processing time for adhering artificial teeth on denture bases. The viscosity of the adhesive composition may be adjusted to the respected processing conditions.

摘要： The disclosure provides a method for producing low molecular weight polytetrafluoroethylene containing less C6-C14 perfluorocarboxylic acids or salts thereof. The method for producing low molecular weight polytetrafluoroethylene includes: (1) irradiating high molecular weight polytetrafluoroethylene to provide low molecular weight polytetrafluoroethylene having a melt viscosity of 1.0×102 to 7.0×105 Pa·s at 380° C.; and (2) irradiating the low molecular weight polytetrafluoroethylene to a dose that does not decompose the low molecular weight polytetrafluoroethylene.
