摘要:
A laminated panel composed of a plastic sheet and a glass sheet bonded to each other through an adhesive layer having a thickness of not more than about 200 microns and composed of a thermoplastic resin having a softening point of less than about 100.degree. C., containing substantially no plasticizer and being plastic at room temperature, said plastic sheet being composed of a resin having a higher softening point than said thermoplastic resin.
摘要:
A novel chelate polymer having the formula: ##STR1## wherein R is a 2-thiazolyl or 2-benzothiazolyl group, is produced by reacting polymaleimide, formaldehyde, and m-aminobenzoic acid in the presence of a solvent, then coupling the resultant reaction product with a diazotized compound of 2-aminothiazole or 2-aminobenzothiazole. The novel polymers thus produced are useful as metal indicators or pH indicators.
