<p>#CMT# #/CMT# Use of polymers obtained by copolymerization of styrene sulfonic acid and/or its ammonium or alkali metal with monomer (I), for enhancing the primary washing power of detergents or cleaning of textiles during washing or cleaning of textile hard surfaces, as compared to deposits of dirt, is claimed. #CMT# : #/CMT# Use of polymers obtained by copolymerization of styrene sulfonic acid and/or its ammonium or alkali metal with monomer of formula (H 2C=C(R)-C(O)-OX) (I), for enhancing the primary washing power of detergents or cleaning of textiles during washing or cleaning of textile hard surfaces, as compared to deposits of dirt, is claimed. R : H or methyl; and X : linear or branched 1-18C-alkyl. Independent claims are included for: (1) removing deposits of dirt, sensitive to bleaching or enzymes, from hard surfaces of textiles, comprising introducing an agent of washing or cleaning and the polymers; and (2) an agent for washing or cleaning containing the polymers. #CMT#USE : #/CMT# The polymers are useful for enhancing the primary washing power of detergents or cleaning of textiles during washing or cleaning of its hard surfaces, as compared to deposits of dirt, and in a washing or cleaning agent for removing deposits of dirt from the hard surfaces of textiles (all claimed), where the textiles comprise cotton textiles. #CMT#ORGANIC CHEMISTRY : #/CMT# Preferred Components: (I) is methyl acrylate, ethyl acrylate, propyl acrylate, isopropyl acrylate, N-butyl acrylate, ethylhexyl acrylate, N-octyl acrylate, N-dodecyl acrylate, and/or n-hexadecyl acrylate. The polymers have an average molecular weight of 500-100000 g/mole, preferably 1000-40000 g/mole. #CMT#POLYMERS : #/CMT# Preferred Components: The deposits of dirt are sensitive to bleaching or enzymes. A fraction of polymers from styrenesulfonic acid monomer is 60 mole%, preferably 75-90 mole%. The fraction of polymers from (I) is 40 mole%, preferably 1-25 mole%. The polymers are added to a bath containing washing or cleaning agents. The agent comprises 0.1-10 mass%, preferably 0.5-5 mass%, of polymers. #CMT#EXAMPLE : #/CMT# 45.32 g of Sodium salt of p-styrene sulfonate and 16.55 g of lauryl acrylate were introduced into a round bottom flask equipped with a magnetic stirrer and a reflux cooler, and then 11.47 g of BlocBuilder MA (RTM: SG1-based alkoxyamine) was added. 200 ml of Dimethyl sulfoxide was purged into the mixture for 30 minutes under an argon atmosphere. A hydrogenation was conducted on the mixture for 4 hours at 120[deg] C. The copolymer was precipitated in acetone/water (95/5 v/v), dissolved again in water and precipitated again in acetone, and then filtered and washed several times with acetone to obtain the polymers.</p> |
