POLYFORMALS AND COPOLYFORMALS AS A PROTECTIVE LAYER AGAINST HYDROLYSIS ON POLYCARBONATE

摘要

The invention relates to a multilayered products which are protected against hydrolysis, comprising at least one layer containing a thermoplast and at least one layer containing at least one polyformal or copolyformal, in addition to compositions containing polyformal or copolyformals and possible additives, in addition to the use of polyformals or copolyformals in the production of a layer which protects against hydrolysis.
