Process for the manufacture of a polymeric material containing interpenetrated polysiloxane-polyacrylic networks |
摘要 |
The polysiloxane network (1) of this polymeric material is formed by (1a) at least one alpha , omega -dihydroxylated polydimethylsiloxane and/or an alpha , omega -dihydroxylated poly(dimethyldiphenyl)siloxane containing at least 70% of dimethylsiloxane units; (1b) a crosslinking agent and/or a bridging agent ensuring the crosslinking as well as a bond between the networks; optionally (1c) a polycondensation catalyst. The acrylic network (2) is formed by (2a) at least one (meth)acrylic monomer containing no hydrophilic functional group; optionally (2b) a crosslinking agent and (2c) a radical polymerization initiator. The polymerization mixture contains all these constituents and sufficient inhibitor of free radical formation to prevent, at the outset, the initiator (2c) producing radicals which, combined with the catalyst (1c) would annihilate the catalytic properties of the latter, to form the network (1) before the network (2). Application: manufacture of articles of all shapes.
