Abstract: The agent contains as film-formers copolymers based on tert.-butyl acrylate and/or tert.-butyl methacrylate with a K value of 10 to 50, obtainable by free-radical polymerisation of A) 75 to 99 % by weight of tert.-butyl acrylate and/or tert.-butyl methacrylate, B) 1 to 25 % by weight of acrylic acid and/or methacrylic acid and C) 0 to 10 % by weight of another monomer which can undergo free- radical copolymerisation, where the carboxyl groups of the copolymers are completely or partially neutralised by amines.

Abstract: Use of iminodiacetic acid derivs. of formula (I) as complexing agent or builder in technical cleaning compsns. for hard surfaces made of metal, plastic, lacquer or glass is new. R = H, 1-4C alkyl or CH2CH2X; Y = COOH, opt. as alkali metal or (substd.) ammonium salt; X is as Y or CONH2, opt. substd. on N. USE/ADVANTAGE - (I) can be included in a wide variety of cleaning compsns. e.g. rust removers; car wash compsns.; electrolytic defatting/derusting/descaling products; steel passivation compsns. high pressure cleaners, etc. Unlike known iminodiacetic acid derivs.; (I) can be formulated without organic solvents. They are extremely effective chelating agents for heavy and alkaline earth metals, esp. Ca. (I) are readily biodegradable and of low toxicity.

Abstract: A terpolymer suitable for use as a film former in hair setting compositions is obtainable by free radical polymerization of 10%-24% by weight of N-vinylpyrrolidone, 46%-74% by weight of tert-butyl acrylate or methacrylate and 16%-30% by weight of acrylic or methacrylic acid, whose carboxyl groups may be partially or completely neutralized with an organic amine, ammonia or a basic alkali metal compound and which has a K value of from 25 to 65.
