General two-monomer (aAa, bBb) bifunctional systems of collective (step) polymerization, a monomer of which (bBb) is characterized by a reactivity asymmetry, are theoretically reconsidered and solved following a simple unitary treatment, that is the

The specific volume υ from -20 to 60°C and the glass transition temperature T g was measured of a a homologous series of linear diolic oligomer fractions constituted by a random perfluoro-poly(oxyethylene-ran-oxymethylene) chain of fairly uniform c

Twelve series of linear oligomers of four different degrees of polymerization ( x n = 8.77−41.55), having a common perfluorinated random copolymeric chain as molecular body and two equal foreign end units of one of the types listed in Table 1, have

Experimental results for five series of linear oligomers of different molecular weights, having a common perfluorinated molecular body and five different pairs of equal foreign end units, generally demonstrate the substantial influence of the chemica

A series of crosslinked polyester resins have been prepared by curing an orthophthalic unsaturated resin containing different amounts of either of two flexibilizers, one bifunctional and the other monofunctional. The samples thus obtained show a vari

N ′-Acryloyl- (AcrNPP), N ′-methacryloyl- (MetNPP) and N ′-acetyl- N -phenylpiperazine (AcNPP) were synthesized and tested as activators in the benzoyl peroxide radical ‘cold curing’ of methyl methacrylate at 40°C. The three amides showed

Samples of oligomers FOMBLIN-ZDOL® (Ausimont Group, Milan) of different molecular weight, with a high diolic bifunctionality CH 2 OH at the ends of a perfluorinated copolymeric chain of the type: [(CF 2 O) p (CF 2 CF 2 O) q ] (p/q = 0.9−1.1) we

The study of a chemical aggregate (molecule or molecular fragment) must proceed through the choice of a qualifying model. The structure of the aggregate (the way in which its model is constructed) can be defined and assigned through a system of level

Modification 3 of isotactic polybutene-1, prepared by crystallization from a solution at room temperature, was studied by dilatometric and X-ray examinations at different temperatures. At high degrees of crystallinity, its specific volume is intermed
