amount of hydrogen bonding between different subunits
number of subunits in the polymer chain
its greater tensile strength
the synthetic composure
"Synthetic resin" is too vague a term for this question to be answered. Xylenes are generally good solvents; you might try that.
ok
All knit fabrics have stretch. In particular spandex and lycra have a large stretch because they are made of synthetic materials with high elasticity. For more information about stretch fabrics, see the page link, further down this page, listed under Sources and Related Links.
Semi-synthetic
synthetic
Semi synthetic or synthetic blend is a combination of synthetic and conventional oil. Full synthetic oil is just that 100% synthetic oil.
Look at it through a loupe (a jeweler's magnifying eyepiece). Natural diamonds will generally have "inclusions" (crud) in them; synthetic ones generally will not.
Composties and Synthetic
Cotton grows from a plant naturally, synthetics are manufactured fibers. Cotton absorbs moisture whereas synthetic fibres generally do not. Cotton is natural and can be eaten by insects whereas synthetic fibres can not, they are around in land fill for hundreds of years. Cotton does not trap moisture, it is permeable, many synthetic fibres are not. Both are polymers.

Generally speaking synthetic materials are man made and do not occur in nature. Example are plastics certain alloys etc. There are some things that can be both synthetic and natural such as some drugs and chemicals
yes
Yes you can mix different brands but I recommend you do not mix different weights. You can even mix synthetic oil with conventional oil. But as the weight of the oil is critical, do not ever mix one weight of oil with another, no matter if it is synthetic or conventional oil.
synthetic fibre = man maid products natural fibre = things that are made from nature
A combination of two or more synthetic(man-made) substances in a new material with different properties.
YES! "Regular" oil is what is mixed with synthetic to make semi-synthetic. Try to use the same brand. I've heard it's not good to mix the different additives that different companies use.
That depends on the type of wig, but generally synthetic fibers.
