Embodiment (I
[0096]
[0097] in:
[0098] [-D-] d -B-O-A-[-O-B'-] a –[-D’-] d’ represents an asymmetric backbone as a bond between polymeric moieties,
[0099] a=0 or 1,
[0100]
[0101] A is always attached to B and / or B' as an aryl-alkyl ether,
[0102] B=*-(CH 2 ) b -*,*-(CH 2 -CH 2 -O-CH 2 -CH 2 )-*,*-(CH 2 -CH 2 -O-CH 2 -CH 2 -CH 2 )-*,*-(CH 2 -CH 2 -CH 2 -O-CH 2 -CH 2 -CH 2 ) -* ,
[0103] B is attached to a (meth)acrylate reactive group as an alkyl ester or to D as a carbamate,
[0104] b=2 to 6,
[0105] B'=*-(CH 2 ) b’ -*,*-(CH 2 -CH 2 -O-CH 2 -CH 2 )-*,
[0106] B' is attached to a (meth)acrylate reactive group as an alkyl ester or to D' as a carbamate,
[0107] b'=2-6,
[0108] D, D' are independently selected from *-(CH 2 ) n -NH-(C=O)-O-*, *-(CH 2 -C(CH 3 ) 2 -CH 2 )-NH-(C=O)-O-*、*-(CH 2 -CH 2 -C(CH 3 ) 2 )-NH-(C=O)-O-*
[0109] D and D' are always attached to B and / or B' via the oxygen atom of a urethane bond,

Embodiment approach
[0308] According to another embodiment, the dental compositions described herein are described below:
[0309] - polymerizable monomer (1): about 1% to about 75% by weight, or about 5% to about 70% by weight, or about 10% to about 65% by weight;
[0310] - polymerizable monomer (2): about 0% to about 60% by weight, or about 0.1% to about 50% by weight, or about 1% to about 40% by weight;
[0311] - polymerizable monomer (3): 0% to about 70% by weight, or about 1% to about 60% by weight, or about 5% to about 50% by weight;
[0312] - one or more initiators: from about 0.1% to about 10% by weight, or from about 0.2% to about 8% by weight, or from about 0.3% to about 6% by weight;
[0313] - one or more fillers: from about 20% to about 95% by weight, or from about 30% to about 90% by weight, or from about 40% to about 85% by weight;
[0314] - one or more additives: 0% to about 10% by weight, or about 0.1% to about 8% by weight, or about 1% to about 5% by weight;

Embodiment 1
[0435] According to general procedure D (solvent based route) 51.5 g of S, 3.30 g of NaOH and 61.1 g of GP were reacted in 150 mL of water to give 90.3 g of PGS. According to General Procedure E, 50.0 g of PGS and 55.4 g of IEM were reacted to give 101.7 g of PGS-IEM.
