Linear polyethyleneimines are synthesized by the hydrolysis of poly(2-ethyl-2-oxazoline), while branched polyethyleneimines are synthesized by ring opening polymerization of aziridine. Different degree of branching can be achieved through different reaction conditions.
In terms of heterocyclic compounds, the properties of hydrogen bonding have been useful to ascribe insights about the stabilization of small rings, of which, the oxirane ([C.sub.2][H.sub.4]O) and aziridine (C2H5N) are some of them [12-15].
Alkylating agents, platinum drugs, antimetabolites, topoisomerase inhibitors and ionizing radiations, nitrosoureas, aziridine compounds, alkyl sulphonates, and triazine compounds are some of the electrophiles that covalently transfer alkyl-groups onto the DNA bases, disrupting the DNA helix and induces DNA breaks [3].
For example, he notes that ERISYS[R] GA-240 is a tetra-glycidyl m-xylene diamine increasingly used as a drop-in replacement for polyfunctional aziridine crosslinkers in adhesive and coating formulations.
For example, ERISYS GA-240, a tetra-functional epoxy reactive modifier, can serve as a drop-in crosslinker replacement for polyfunctional aziridine (PFAZ) in coatings and adhesives.
Aziridine, 1-vinyl- (13.10%), n-propylacetate (5.64%) and ethanol,2-(2- aminoethoxy) (5.28%) are three of the higher percentage compounds than others in aqueous extract, meanwhile 1-decosene (21.81%), lupeol (10.40%) and cyclobutanol (6.61%) are the higher percentage compounds than others in methanol extract.Furthermore, provisional estimates that the detectable secondary metabolites in S.
The DOJ said that "[t]he presence of shabu precursors Dimethyl and Phenylaziridine (Aziridine) in the clandestine laboratory is a prima facie proof of manufacture of dangerous drugs."

Aziridine 2-methyl- is an imine which is widely spread in ten sampling stations out of thirteen (Table 7).
Polyamines can be prepared hy ring-opening polymerization of aziridine and aziridine through a cationic mechanism, as the three- and four- membered rings contain enough ring strain to be polymerizable (13).
They were then formulated into ambient cure clearcoatings with aziridine crosslinking.
