Galimberti and co-workers synthesized ethylene/ propylene/4-iodo-l-butene terpolymers with a V(acac)3/AlEt2X catalyst (X = Cl, I). The copolymers prepared were amorphous, having at least 35 wt % propylene content, and possessed a bimodal molecular weight distribution of high polymer (MW > 500 000) and oligomers. The preparation of crystalline copolymers of propylene with linear ft>-halo-olefins using TiCla/EtsAl has also been reported by Hoechst. ... 

When ft>-haloolefins are used as comonomers, the primary G—X bond may be exploited as a protecting group to be unmasked after polymerization. Ethyl-ene/propylene/4-iodo-l-butene terpolymers synthesized by Galimberti et al. have been quantitatively dehydrohalogenated with f-BuOK/18-crown-6 to give ethylene/propylene/1,3-butadiene terpolymers in which the diene (incorporated at up to 3.6 wt %) has exclusively a 1,2-incorporation microstructure. Copolymers of propylene or 4-methyl-1-pentene with... 

Blends of PE with PP are immiscible thus, for enhancement of the interphasial interaction, copolymerization has been used (Da Silva et al 2000, 2001). For example, m-LLDPE was blended with ethylene-propylene-butene-1 terpolymer (fer-PP 2.9/92.4/4.7 wt%). Even in the presence of immiscibihty, the enhancement of interactions at 20 wt% of fer-PP sufficiently improved processability and performance to warrant commercial interest (Cho et al. 1997).

Krishen [42] obtained the products listed in Table 4.10 by pyrolysis of ethylene-butadiene rubber and ethylene-propylene-diene terpolymer. He showed that the 2-methyl-2-butene peak was linear with the natural rubber content of the sample. Styrene-butadiene rubber was determined from the peak area of the 1,3-butadiene peak. The ethylene-propylene-terpolymer content was deducted from the 1-pentane peak area of the pyrolysis products. 

Finally, we mention the crystallinity measurements in ethylene-propylene-butene-1 terpolymers (f38). The catalytic system used provides relatively poor randomness (rj r2 = 2.5) but the incorporation of a small amount of butene-1 in copolymers (5-10mol-%) significantly reduces the total crystallinity. 

There seem to be only limited published studies of calcium carbonate s influence on the mechanical properties of thermoplastics and elastomers. Clearly, the Young s modulus and tensile strength are increased. H. Kim et al. [98] showed the addition of calcium carbonate into polypropylene, poly(propylene-random ethylene) copolymer, and poly( propylene-ethylene-butene) terpolymer increases Young s modulus and decreases elongation to break. Kwon et al. [99] observed the same trend for high-density polyethylene, low-density polypropylene, and linear low-density polyethylene compounds that tensile stress of calcium carbonate-filled compounds were higher than unfilled systems. 

A material, such as (a) a terpolymer of propylene, ethylene and butene-1, (b) a polyolefin composition, which includes about 31 to 39% of a copolymer of propylene and ethylene and about 58 to 72% of a terpolymer of propylene, ethylene and butene-1 or (c) a polyolefin composition, which includes about 30 to 65% of a copolymer of propylene and butene-1 and about 35 to 70% of a copolymer of propylene and ethylene, is irradiated and extruded through a die in the presence of a physical expanding agent and a cell nucleating agent to produce a structure having a density, which is at least 10 times less than the initial density of the material. The foam articles exhibit improved flexibility and low temperature toughness compared to conventional propylene polymer materials. 

The list of polymers known to respond satisfactorily to permanganic etching is now long and continually growing. It consists of linear and branched polyethylene, four isotactic polyolefins (polypropylene, polystyrene, poly(4-methylpentene-l) and poly(butene-l)), related atactic polymers, poly(vinylidene fluoride) (hereafter denoted PVF2), PEEK, and poly(ethylene terephthalate) (PET), together with various copolymers and others such as ethylene propylene rubbers and ethylene-propylene-diene (EPDM) terpolymer.
