摘要： A polymerisation process for preparing a polymerisable composition comprising a polymer, e.g. (poly)methyl acrylate, and a monomeric component, e.g. methyl methacrylate, which process employs selective catalytic polymerisation of the methyl acrylate monomer, e.g. using an organosilicon catalyst, in the presence of the methyl methacrylate monomer to produce a solution or dispersion without the need for initially preparing the polymer in isolation.

摘要： A method for generating, from initial content data, output content data for provision to one or more receivers, wherein the initial content data is encoded according to a coding scheme, wherein for a quantity of data encoded according to the coding scheme, the coding scheme provides a mechanism for including in the quantity of encoded data additional data such that a decoder for the coding scheme, upon decoding the quantity of encoded data, does not use the additional data to generate decoded data, the method comprising: selecting one or more portions of the initial content data; for each selected portion, generating a data construct that comprises a plurality of data structures, each data structure comprising data, including a version of the selected portion, that is encrypted using a corresponding encryption process different from each encryption process used to encrypt data in the other data structures, wherein the data construct is arranged such that using a decryption process that corresponds to the encryption process for one data structure on the encrypted data in each data structure in the data construct produces a quantity of data encoded according to the coding scheme that uses the mechanism so that a decoder for the coding scheme would not use any data structure in the data construct other than said one data structure; and using the generated data constructs in the initial content data instead of their corresponding selected portions to form the output content data.
