Title: Improvements relating to cyclized rubber
IPC: C08K5/29
Filed: 1942-08-31
Abstract: In order to improve its keeping properties, compositions containing cyclized rubber are admixed with a product obtained by condensing an aldehyde with a polyalkylenepolyamine, having the formula R.RNR1[NRR1]xNR.R in which R is hydrogen or an aliphatic radicle, R1 is alkylene and x is a whole number, and in which the groups R of the group NR.R may link up to form a heterocyclic ring with carbon, sulphur or the group NH.  The use of the products in moistureproof paints and compositions, which may be applied to paper, is mentioned. In examples: (1) formaldehyde is condensed, in various proportions with diethylenetriamine, triethylenetetramine and tetraethylenepentamine, sometimes in the presence of benzene; (2) butyraldehyde is condensed with diethylenetriamine and tetraethylenepentamine; (3) hexaldehyde, a -ethyl-b -propylacrolein and heptaldehyde are condensed with tetraethylenepentamine; (4) formaldehyde, ammonia and tetraethylenepentamine are condensed; (5) crotonaldehyde is condensed with diethylenetriamine and the product treated with 2-ethylhexylbromide; (6) hexaldehyde is condensed with diethylenetriamine and the product treated with hexylbromide; (7) N : N1111-dihexyltetraethylenepentamine prepared from tetraethylenepentamine and hexylbromide is condensed with butyraldehyde; (8) N : N1111-dibenzyltetraethylenepentamine, prepared from benzylchloride and the parent base is condensed with hexaldehyde; (9) N : N1 : N11-tri-(o-methylcyclohexyl) diethylenetriamine, prepared from ethylenedibromide and o - methylcyclohexylamine is condensed with formaldehyde; (10) butyraldehyde is condensed with N-(b -morpholylethyl) ethylene diamine and di-(b -morpholylethyl) amine; (11) butyraldehyde and hexaldehyde are condensed with N-(b -morpholylethyl) triethylenetetramine, prepared from tetraethylene pentamine and b  : b 1-di-(chlorethyl) ether; (12) butyraldehyde and hexaldehyde are condensed with N : N11-di-(b -morpholylethyl) diethylenetriamine which is prepared from tetraethylenepentamine and b  : b 1-di-(chlorethylether); (13) paraformaldehyde is condensed in benzene with triethylenetetramine.  The polyalkylenepolyamines may be mixed with simple amines such as methylamine, benzylamine and furfurylamine for use in the condensation.  The use of polyalkylenepolyamines containing the thiomorpholyl nucleus, which may be made from dihalogendiethylthioether and the polyalkylenepolyamine is mentioned. The corresponding piperazyl compounds prepared from dihalogendiethylamine and the polyalkylenepolyamine may also be used.ALSO:In order to improve their keeping properties compositions containing cyclized rubber are admixed with a product obtained by condensing an aldehyde with a polyalkylene-polyamine, having the formula <FORM:0568787/V/1> in which R is hydrogen or an aliphatic radicle, R1 is alkylene and x is a whole number, and in which the groups R of the group NR.R may link up to form a heterocyclic ring with carbon sulphur or the group NH.  The use of the products in moistureproof paints and compositions, which may be applied to paper is mentioned.  In examples: (1) formaldehyde is condensed, in various proportions with diethylenetriamine, triethylene tetramine, and tetraethylenepentamine, sometimes in the presence of benzene; (2) butyraldehyde is condensed with diethylenetriamine and tetraethylenepentamine; (3) hexaldehyde ethyl-3-propylacrolein and heptaldehyde are condensed with tetraethylenepentamine; (4) formaldehyde, ammonia and tetraethylenepentamine are condensed; (5) crotonaldehyde is condensed with diethylenetriamine and the product treated with 2-ethylhexylbromide; (6) hexaldehyde is condensed with diethylenetriamine and the product treated with hexylbromide; (7) N : N1111-dihexyltetraethylenepentamine prepared from tetraethylenepentamine and hexylbromide is condensed with butyraldehyde; (8) N : N1111-dibenzyl tetraethylene pentamine, prepared from benzylchloride and the parent base is condensed with hexaldehyde; (9) N : N1 : N11-tri - (o - methylcyclohexyl) diethylenetriamine, prepared from ethylenedibromide and o-methylcyclohexylamine is condensed with formaldehyde; (10) butyraldehyde is condensed with N-b (-morpholylethyl) ethylenediamine and di-(b -morpholylethyl) amine; (11) butyraldehyde and hexaldehyde are condensed with N-(b -morpholylethyl) triethylenetetramine prepared from tetraethylenepentamine or b b 1-di(chlorethyl) ether; (12) butyraldehyde and hexaldehyde are condensed with N : N11-di(b -morpholylethyl) diethylenetriamine which is prepared from tetraethylenepentamine and b  : b -di(chlorethylether); (13) paraformaldehyde is condensed in benzene with triethylenetetramine. The polyalkylene polyamines may be mixed with simple amines such as methylamine, benzylamine and furfurylamine for use in the condensation.  The use of thio polyalkylene polyamine compounds which may be made from dihalodiethylthioether and the polyalkylenepolyamine is mentioned.
