摘要:
A synthetic resin composition is prepared by mixing various polymers which differ, above all, in their second order transition temperature; the composition can also contain a filler, an epoxide resin and an alcoholate. The composition is preferably obtained in the form of granules, the particle diameter being within the range from 1 to 10 mm. It is used as a starting material for the production of vibration-damping sheets.
摘要:
An aqueous plastic dispersion which is based on three vinyl polymers differing in type and properties, and which additionally contains a filler, is prepared by mixing a mixture of aqueous dispersions of the polymers in question with an aqueous suspension of the filler. The most important distinguishing characteristic of the polymers mentioned is their glass transition temperature. A fibrous material is employed as the filler. The plastic dispersion is suitable as a starting material for the preparation of sheets with vibration-damping properties.
