METHOD FOR SURFACE HARDENING SUBSTANCES BY APPLICATION OF PARTICULARLY TRANSPARENT POLYMETHACRYLATE LAYERS |
摘要 |
<p>A method for surface coating materials with a layer of thermoplastic polymethacrylate involves using a mixture of (a) methyl methacrylate-based polymer and (b) an acrylic copolymer with reactive monomer units, which is applied at a temperature enabling the formation of a chemical bond between the layer and the substrate. A method for the surface coating of materials with a layer of thermoplastic polymethacrylate obtained by mixing polymers (a) and (b), where (a) is derived from (A) 20-100 wt% methyl methacrylate, (B) 0-80 wt% (meth)acrylate of formula CH 2=CR 1-COOR 2 (I) other than (A) and (C) 0-40 wt% other unsaturated comonomers, and (a) may also contain 0-80 parts by weight (pts. wt.) other polymers and 0-150 pts. wt. conventional additives per 100 pts. wt. (a.A)-(a.C), (b) is derived from (A) 20-99 wt% (I), (B) 1-80 wt% unsaturated reactive comonomers other than (I), and (b) may also contain other components as in (a). R 1H or methyl; R 21-18C alkyl or cycloalkyl, or phenyl or naphthyl . The polymethacrylate layer is applied to the substrate at a temperature which enables the formation of a chemical bond between the layer and the substrate material. An independent claim is also included for composite materials obtained by this method.</p> |
