Abstract
Plastic material compositions which comprise a plastic material matrix containing a benzhydrol-tetracarboxylic acid tetraester as a plasticizer are disclosed. The plasticizer is firmly anchored within the matrix such that migration of the plasticizer, and any other optionally present matrix components having a molecular weight of at least 100, are inhibited within the matrix. The plasticizer and matrix components are inhibited from eluting from the matrix when the matrix is brought in intimate contact with a liquid or solid material. These compositions are particularly useful as shaped bodies possessing highly elastic and adhesive characteristics.
