Title: Solvent soluble hydroxyl gp. contg. copolymers - made by reacting unsatd. mono:carboxylic acid with mono-glycidyl cpd. in vinyl monomer, and copolymerising with further vinyl monomers
Inventor: DALIBOR HORST DIPL CHEM DR
IPC: C08G18/62

Abstract: Prepn. of organic solvent-soluble, OH-contg. copolymers is claimed which are based on vinyl cpds., alpha, beta-unsatd. monocarboxylic acids (I) and monoglycidyl cpds. (II), in which the COOH gp. of the (I) is bound as an ester to the (II). The copolymers are made by first esterifying the (I) with the (II) in the presence of >=1 vinyl cpd. Subsequently, copolymerisation is carried out in an inert solvent, opt. with the addn. of further vinyl cpd(s). such that during the copolymerisation stage, >=2 further vinyl cpds. are present in addn. to the monomeric prod. from the esterification stage. The OH-contg. copolymers are obtd. as clear colourless organic solvent solns., which are free from the clouding and brown colour of prior art materials of this type. The process is suitable for industrial scale prodn. and is not critical w.r.t. reaction conditions. The prods. are useful as components in coating resin compsns. for use with crosslinking agents such as polyisocyanates and aminoplast resins.

Title: Watch strap clasp with spring and ratchet - has integral top link and detent spring for simple mfr.
Inventor: GLOSS HEINZ
IPC: A44C5/24
Filed: 1978-12-05
