Wavelets in 1989 : An extended summary,on of low molecular weight polystyrene adds further reinforcement. (For example, this addition to a SBS polymer of 30 wt. % styrene to give an overall composition of 40 wt. % styrene increased the modulus at an extension ratio of 5 from 23 to 44 kg. /cm.. at a strain rate of 31.5 min..)Lymphocyte 发表于 2025-3-26 08:38:35

They are more complex than molecules of either homopolymers or random copolymers, and they are more difficult to synthesize in a well-defined form, but they have also many properties which cannot be found in homopolymers or random copolymers. If the different sequences of
